Description

Technical Field

[0001] This application relates to the technical field of Chinese chess engines, and in particular, to a method for operating a Chinese chess engine and related devices. Background Art

[0002] This section aims to provide background or context for the embodiments of the present application described in the claims. The descriptions herein are not admitted to be prior art merely because they are included in this section.

[0003] Currently, there are an endless number of chess applications derived from Chinese chess engines. Whether it is a PC client, a mobile device, or a web application, various Chinese chess applications have emerged. However, most of the existing Chinese chess applications currently only stay on the surface, with weak support for general FEN positions and PGN chess scores. Coupled with the outdated technology stacks implemented in current Chinese chess applications in the front-end field, and the entanglement of the core chess-playing functions with UI rendering, it is rather troublesome to migrate. In addition, the current Chinese chess engines do not have a perfect message notification mechanism, and it is impossible to timely notify developers for unified processing of various operations and changes on the chessboard. At the same time, the moves supported by most current Chinese chess applications are different and not unified, and the conversion of various moves during chess-playing gives developers a huge headache.

[0052] The following will describe the principles and spirit of this application with reference to several exemplary embodiments. It should be understood that these embodiments are only provided to enable those skilled in the art to better understand and then implement this application, rather than limiting the scope of this application in any way. On the contrary, these embodiments are provided to make this application more thorough and complete, and to be able to convey the scope of this application to those skilled in the art completely.

[0053] According to the embodiments of this application, a method, device, electronic device, and storage medium for operating a Chinese chess engine are provided.

[0054] In this text, it should be understood that any number of elements in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0055] The principles and spirit of the present application will be elaborated in detail below with reference to several representative embodiments of the present application. Summary of the Invention

[0057] In the current related technologies, the moves supported by most Chinese chess application programs are different and not unified. These moves include vertical line moves in Chinese, digital vertical line moves, UCCI coordinate moves, chessboard grid moves, and other types of moves. These moves are not interchangeable. When third-party developers develop Chinese chess application programs through a chess engine, they often need to manually convert various moves, or can only develop based on a single move provided by the development engine, which brings inconvenience to program development.

[0058] To solve the above problems, the present application provides a method for running a Chinese chess engine, specifically including:

[0059] First, determine the type of the initial move of Chinese chess according to the characteristics of the input initial move of Chinese chess; then determine the starting position and the target position of the target chess piece in the initial move according to the type of the initial move; finally, convert the initial move into a digital move according to the starting position and the target position, so as to unify the various input Chinese chess moves into digital moves, avoid various difficulties encountered in manual move conversion, and enable the Chinese chess engine of the present application to be applicable to various Chinese chess moves, providing convenience for third-party developers.

[0060] After introducing the basic principles of the present application, various non-limiting embodiments of the present application will be specifically introduced below.

[0061] Overview of Application Scenarios

[0062] Refer to Figure 1, which is a schematic diagram of the application scenario of the operation method of the Chinese chess engine provided by an exemplary embodiment of the present application. This application scenario includes a terminal device 101, a server 102, and a data storage system 103. Among them, the terminal device 101, the server 102, and the data storage system 103 can all be connected through a wired or wireless communication network. The terminal device 101 includes, but is not limited to, a desktop computer, a mobile phone, a mobile computer, a tablet computer, a media player, a smart wearable device, a personal digital assistant (PDA), or other electronic devices capable of implementing the above functions. The server 102 and the data storage system 103 can both be independent physical servers, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms.

[0063] The server 102 is used to provide the operation service of the Chinese chess engine to the users of the terminal device 101. A client communicating with the server 102 is installed in the terminal device 101, and the user can obtain data in the Chinese chess engine through this client. During the operation of the Chinese chess engine, the client inputs the initial move of Chinese chess by calling the input components (such as a touch screen, a keyboard, a camera, etc.) of the terminal device 101; the client sends the initial move of Chinese chess to the server 102. The server 102 can convert the input initial move into a digital move through the Chinese chess engine, so that the user can directly play chess through the input initial move. Optionally, after the initial move of Chinese chess is input to the client, the client can also convert the input initial move into a digital move through the Chinese chess engine.

[0064] Various data related to move conversion are stored in the data storage system 103. The server 102 can randomly retrieve various data related to move conversion from the data storage system 103.

[0065] Next, in combination with Figure 1 the application scenario, the operation method of the Chinese chess engine according to an exemplary embodiment of the present application will be described. It should be noted that the above application scenario is only shown for the convenience of understanding the spirit and principle of the present application, and the embodiments of the present application are not limited in this regard. On the contrary, the embodiments of the present application can be applied to any applicable scenario.

[0066] Exemplary Method

[0067] Refer to Figure 2, an exemplary embodiment of the present application provides a method for running a Chinese chess engine, and the method includes the following steps:

[0068] S101, determining the type of the initial move based on the characteristics of the initial move of Chinese chess input.

[0069] Specifically, when the initial move input to the Chinese chess engine is obtained, the type of the initial move can be determined according to the characteristics of the initial move. The characteristics of the initial move can be notation characteristics, that is, each type of move corresponds to a notation characteristic. For example, those containing Chinese belong to the Chinese vertical line method, the grid serial number move contains arrow characters, and the UCCI coordinate move is generally represented by a combination of two pairs of letters and numbers as the starting point grid coordinate and the target point grid coordinate. Optionally, a neural network model can also be trained to identify the type of the initial move.

[0070] It should be noted that the engines referred to in the present application are all engines in the computer field, and the moves of Chinese chess represent the positions where a certain piece in Chinese chess moves from and to.

[0071] S102, determining the starting position and the target position of the target piece in the initial move based on the type of the initial move.

[0072] Specifically, after determining the type of the initial move, according to the type of the initial move, the starting position and the target position of the target piece in the initial move are determined. Among them, the starting position is the current position of the target piece, and the target position is the position where the target piece will reach.

[0073] In some embodiments, the types of the initial move include the Chinese vertical line move, the digital vertical line move, the UCCI coordinate move, and the grid serial number method; determining the starting position and the target position of the target piece in the initial move based on the type of the initial move includes:

[0074] In response to determining that the type of the initial move is the digital vertical line move, determining the starting position based on the part before the preset move character in the initial move, and determining the target position based on the starting position, the preset move character, and the part after the preset move character in the initial move;

[0075] In response to determining that the type of the initial move is the Chinese vertical line move, converting the initial move into a digital vertical line move, and determining the starting position and the target position based on the initial move converted into the digital vertical line move;

[0076] In response to determining that the type of the initial move is the UCCI coordinate move, determine the starting position based on the first two characters of the initial move, and determine the target position based on the last two characters of the initial move;

[0077] In response to determining that the type of the initial move is the grid serial number method, determine the starting position based on the number before the arrow character in the initial move, and determine the target position based on the number after the arrow character in the initial move.

[0078] In specific implementation, when determining that the type of the initial move is the digital vertical line move, first determine the preset movement character in the initial move. The preset movement character mainly refers to the character indicating movement. For example, the movement character "." represents translation, the movement character "+" represents forward movement, and the movement character "-" represents backward movement. It should be noted that to avoid confusion with the characters indicating directions, the preset movement character is the movement character after the letter. For example, in "+C+2", "+C" represents the front cannon (the cannon in the front), and "+C+2" represents the front cannon moving forward two grids. After determining the preset movement character, the starting position can be determined according to the part before the preset movement character in the initial move, and the target position can be determined according to the starting position, the preset movement character, and the part after the preset movement character in the initial move. Optionally, the starting position can be determined according to the current Chinese chess situation in the Chinese chess engine and the meaning of the part before the preset movement character, and then the target position can be determined according to the current Chinese chess situation, the starting position, the preset movement character, and the meaning of the part after the preset movement character in the initial move. It should be noted that the situation in this application is for the Chinese chess field and is used to describe the distribution of the pieces of the two players currently playing chess.

[0079] When determining that the type of the initial move is the Chinese vertical line move, since this move is not easy to process by the program, therefore, we convert the Chinese vertical line move into the digital vertical line move according to the relevant Chinese mapping table and characteristic mapping rules (part of the mapping table includes the mapping of piece types, such as converting the cannon to C, the mapping of converting Chinese numbers to Arabic numbers, such as converting two to 2, and the mapping of converting the movement type to a symbol, such as converting horizontal movement to "."). For example, convert "cannon two horizontal five" to: "C2.5", and then continue to process through the processing method of the digital vertical line move as described above, and determine the starting position and the target position according to the initial move converted into the digital vertical line move.

[0080] When it is determined that the type of the initial move is the UCCI coordinate move, the starting position is determined according to the first two characters of the initial move, and the target position is determined according to the last two characters of the initial move. For example, in "h2e2", the starting position can be determined according to "h2", and the target position can be determined according to "e2". Among them, h and 2 in "h2" respectively represent the abscissa and ordinate in the preset chessboard.

[0081] When it is determined that the type of the initial move is the grid serial number move, the starting position can be determined according to the number before the arrow character in the initial move, and the target position can be determined according to the number after the arrow character in the initial move. For example, in "170—>167", "—>" is the arrow character, 170 represents the position numbered 170 in the preset chessboard, and 167 represents the position numbered 167 in the preset chessboard.

[0082] In some embodiments, after determining the type of the initial move of Chinese chess based on the characteristics of the input initial move, the method further includes:

[0083] In response to determining that the type of the initial move is the digital move, the initial move is not transformed.

[0084] Specifically, when it is determined that the type of the initial move is the digital move, the initial move does not need to be transformed.

[0085] S103, transform the initial move into a digital move based on the starting position and the target position.

[0086] Specifically, after determining the starting position and the target position of the initial move, the initial move is transformed into a digital move according to the starting position and the target position.

[0087] In some embodiments, transforming the initial move into a digital move based on the starting position and the target position includes:

[0088] Determine the first digital number corresponding to the starting position and the second digital number corresponding to the target position based on the preset list of piece position numbers;

[0089] Perform numerical expansion on the first digital number based on a preset algorithm, and transform the initial move into a digital move based on the expanded first digital number and the second digital number; or, perform numerical expansion on the second digital number based on a preset algorithm, and transform the initial move into a digital move based on the expanded second digital number and the first digital number.

[0090] Specifically, refer to Figure 3, where in the preset list of piece position numbers, each position on the chessboard corresponds to a numerical number. For example, Figure 3 the numerical number corresponding to the position of the black rook in Figure 3 is 051. Optionally, the specific value of the numerical number can be set as needed and is not limited herein. After determining the starting position and the target position of the target piece in the initial move, the first numerical number corresponding to the starting position and the second numerical number corresponding to the target position can be determined according to the preset list of piece position numbers. The numerical move in this application mainly represents a move by a single number. For example, the simplest numerical move can be the direct addition of the first numerical number and the second numerical number. For example, if the first numerical number corresponding to the starting position of a certain move is 40 and the second numerical number corresponding to the target position is 60, then 100 can be used to represent the numerical move corresponding to this move. However, if the numerical move is directly determined by the first numerical number and the second numerical number, it will lead to the inability to distinguish two different moves in some cases. For example, if the first numerical number corresponding to the starting position of a certain move is 30 and the second numerical number corresponding to the target position is 70, and the two are directly added, then the numerical move for this time is also 100, but this move is significantly different from the first move with the same numerical move of 100. To avoid this situation, it is necessary to numerically expand the first numerical number or the second numerical number through a preset algorithm, and then determine the current numerical move based on the expanded numerical number. The preset algorithm can be set as needed and is not limited herein. For example, if the first numerical number corresponding to the starting position of a certain move is 40 and the second numerical number corresponding to the target position is 60, and the preset algorithm is to expand the first numerical number by 8 times, then the numerical move at this time is: 40 * 8 + 60 = 3260. When the first numerical number is 30 and the second numerical number is 70 at this time, the corresponding numerical move is: 30 * 8 + 70 = 2470. Thus, each numerical move has uniqueness.

[0091] In some exemplary embodiments, the method further includes:

[0092] Determining the legality of each move based on the starting position and the target position of the piece to be moved in each move;

[0093] In response to collecting an illegal move record, sending the illegal move record to a third-party developer so that the third-party developer configures the corresponding UI rendering special effects.

[0094] In specific implementation, some preset rules of Chinese chess can be used, and the legality of each chess move can be determined based on the starting position and the target position of the piece to be moved in each chess move. Optionally, it can be checked whether there is a piece at the starting point. If there is no piece, the move is illegal. It can also be checked whether there is a piece of the moving side at the target point. If there is a piece of the moving side blocking the way, the move is illegal. In addition, the legality of each chess move can be judged according to the different types of the target piece. For example, the general can only move in the four directions of up, down, left, and right within the general's tent and can only move one step at a time. After determining the legality of each chess move, when an illegal chess move record is collected, the illegal chess move record is sent to the third-party developer so that the third-party developer can configure the corresponding UI rendering special effects. It should be noted that in this application, the legality of the chess move is actively verified, and when an illegal chess move is monitored, the illegal chess move record is actively sent to the third-party developer. The third-party developer can configure the corresponding UI rendering special effects according to the illegal chess move record, which is convenient for the third-party developer to customize the UI rendering special effects personalizedly.

[0095] In some embodiments, the method further includes:

[0096] In response to determining that a checkmate situation appears in the current chess game, the checkmate situation is sent to the third-party developer so that the third-party developer can configure the corresponding UI rendering special effects.

[0097] In response to determining that a stalemate situation appears in the current chess game, the stalemate situation is sent to the third-party developer so that the third-party developer can configure the corresponding UI rendering special effects.

[0098] In specific implementation, some preset rules of Chinese chess can be used to determine whether a checkmate situation appears in the current chess game. Optionally, taking the perspective of the opponent's general or marshal as a reference, all the opponent's pieces in the entire chessboard array can be traversed. As long as any one piece can reach the position of the opponent's general or marshal within one move, it is considered that there is a checkmate situation at this time. Optionally, some preset rules of Chinese chess can be used to determine whether a stalemate situation appears in the current chess game. Optionally, after a certain side makes a move, first judge whether there is a check situation. If there is no check, it is not a stalemate. If there is a checkmate situation, then traverse all our pieces and use the virtual move (that is, try to make a move and then revoke it. The actual chessboard does not change, but more information can be obtained after trying to make a move) method to let all pieces try to take one step using their respective legal move methods to see if a move that can solve the checkmate situation can be achieved. If all the moves of all pieces cannot solve the situation, then it can be judged that the current situation has reached a stalemate against the opponent. When a checkmate situation or a stalemate situation is monitored, the checkmate situation or the stalemate situation is sent to the third-party developer so that the third-party developer can configure personalized UI rendering special effects.

[0099] In most existing Chinese chess engines, the logic layer for playing chess is more or less bound to the UI rendering layer. When these basic engine libraries were designed, the strong portability of the engine was not considered, and a specific UI framework was used in the development process. This makes it extremely difficult to extract the logic layer of the engine into another UI framework. However, with the continuous development of front-end technologies, browser compatibility issues have been gradually resolved, and the emergence of more and more view-layer UI rendering frameworks has brought more choices to developers, but at the same time, it has also exposed the drawbacks brought by the strong binding to the UI framework to the engine library. To avoid these drawbacks, in some embodiments, the logic layer of the Chinese chess engine is isolated from the UI rendering layer, so that the logic layer can access different UI-rendered applications, thereby making the Chinese chess engine of the present application highly portable.

[0100] In some embodiments, the Chinese chess engine of the present application provides static methods for parsing and generating PGN chess scores. Third-party developers can input existing PGN chess scores in the form of strings, and then the current chess score structure can be parsed, and a quick step-by-step method can be generated to facilitate step-by-step review. Among them, PGN is used to record the norms of Chinese chess games. In addition to containing the moves, it also includes other information and annotations of the chess game. Specifically, when the Chinese chess engine of the present application receives an incoming PGN chess score, it will first perform feature parsing on the chess score, parse and process the two sides of the current chess score, the starting situation, the win-loss situation, the game name, the game time, the specific move records, etc. to form a PGN object. Then, according to the move records in this PGN object, a number is set for each move, and a method that can execute the chess-playing operation several times in a loop according to the number is generated, and a quick method for switching the corresponding move according to the number is passed in. Third-party developers can directly input the target number of moves to update the current chessboard to the state of the target number of moves.

[0101] In some embodiments, the Chinese chess engine of the present application provides a complete cli command-line tool that developers can choose to install and use as needed, supporting various operations such as quickly playing chess and reviewing in the command line to improve efficiency. When playing chess, when the user inputs a certain move, the doMove method of the Chinese chess engine instance is called to play chess, and the command-line tool will display all types of move information of the current move in real time, facilitating developers to quickly obtain different moves for each step. The user can also use the free mode and use keys such as the up, down, left, and right arrow keys and the space bar and enter key to perform more efficient chess-playing operations.

[0102] The operation method of the Chinese chess engine provided by this application first determines the type of the initial move according to the characteristics of the initial move of Chinese chess input; then determines the starting position and the target position of the target chess piece in the initial move according to the type of the initial move; finally, converts the initial move into a digital move according to the starting position and the target position, so as to unify various Chinese chess moves input into digital moves, avoid various difficulties encountered in manual move conversion, and enable the Chinese chess engine of this application to be applicable to various Chinese chess moves, providing convenience for third-party developers. At the same time, through a perfect message notification mechanism, this application can notify the outside world of most details of the user's operation on the chessboard by dispatching subscription messages, facilitating third-party developers to handle various special situations more flexibly. In addition, the logic layer and the UI rendering layer of the Chinese chess engine of this application are isolated, making it more convenient for third-party developers to connect the logic layer to various types of UI rendering libraries.
