Embodiment Construction

[0036] The present invention is described in detail below by specific embodiment and accompanying drawing:

[0037] Referring to Figure 1 and Figure 2, a multi-person item exchange model and its solution, the steps include:

[0038] Step 1: Select Barter Request N AB The real object A is used as the root node of the barter tree, and the current barter tree is recorded as T;

[0039] Step 2: After searching the database, if a barter request N is found BC The object is the same as the leaf node B of the current barter tree T, then use N BC Extend barter tree T;

[0040] Step 2: Because there is no barter loop formed, continue to search the database, if you find a barter request N CD , N CF , N CG The object is the same as the leaf node C of the current barter tree T, then use N CD , N CF , N CG Extend barter tree T;

[0041] Step 4: Similarly, request N using barter DE and N EA Extend barter tree T;

[0042] Step 5: After the above expansion, the following barter tr...

Abstract

An article exchange model participating in by a numbers of persons is prepared as supposing n types of article being able to be exchanged, applying binary set A and B as one article exchange request being recorded as NAB to present to exchange article A for article B, setting up a numbers of loops and making maximum nodes be contained in certain loop, setting article A to be article held by article exchange person and article B to be article to be exchanged by exchange person as well as article exchange loop to be closed loop with partial nodes. Its solving method is also disclosed.

Description

technical field [0001] The patent of the present invention relates to an item exchange model participated by multiple people, in particular to a solution method of the item exchange model, which belongs to the technical field of logistics optimization. Background technique [0002] Item exchange means that people exchange their own items with others for what they need. As early as the stage of primitive society, people began to exchange with the items they earned from their own labor. With the gradual expansion of the social scale, people need more and more items for life and work. However, due to the limited scope of everyone's work activities, item transactions are often limited to a small area, and the type and quality of items are difficult to meet the demand. [0003] With the development of the computer Internet, people can get more and richer information, which also expands the scope of item exchange. However, item exchange activities are generally limited to two p...
