Solution Overview

Problem

Players deliberately lower their ratings by playing with less effort to unfairly participate in game events and obtain handicaps, necessitating a solution to prevent and correct such behavior.

Innovation Solution

An information processing device calculates ability values based on reliable game records, distinguishing between games with and without reliability confirmation, using partial ability values to ensure the calculated ability reflects valid proficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If ability value is calculated based on all game records, then calculation is simple and continuous, but players can deliberately lower their rating by playing with less effort

Engineering Contradiction:
Improveease of ability value calculationVSAvoidreliability of ability value
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent segments game records into two categories: reliable records (played with normal effort) and unreliable records (played with reduced effort). By separating these segments, the system can calculate ability value based only on reliable records, preventing players from manipulating their rating through deliberate low-effort play while maintaining calculation simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements feedback by detecting when a player plays with reduced effort and excluding those specific game records from ability value calculation. This feedback mechanism identifies and penalizes manipulative behavior by removing the impact of low-effort games, thereby maintaining the reliability of ability value while keeping the calculation process straightforward.

Inventive Principle:
Principle #23Feedback

2Reliability

If ability value is calculated based on reliable records only, then rating manipulation is prevented, but calculation complexity increases

Engineering Contradiction:
Improvereliability of ability valueVSAvoidcomplexity of ability value calculation
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary action by determining in advance which game records are reliable and which are unreliable before calculating ability value. By pre-classifying records based on effort level and game context, the system avoids complex real-time analysis during ability value calculation, thus maintaining reliability while managing computational complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mechanism that acts as a filter between game records and ability value calculation. This intermediary component (the determination unit) selectively includes or excludes records based on reliability criteria, simplifying the overall calculation process while ensuring only trustworthy data influences the ability value.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If all game records are used for ability value calculation, then continuous updates are possible, but inaccurate rankings result from deliberate rating lowering

Engineering Contradiction:
Improvecontinuity of ability value updatesVSAvoidprecision of ability value
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system segments game records into reliable and unreliable categories, then uses only reliable segments for ability value calculation. This segmentation maintains continuous updates by processing all games while ensuring precision by excluding inaccurate records, thus resolving the contradiction between productivity and measurement precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The feedback mechanism continuously monitors game effort levels and adjusts which records are included in ability value calculation. This feedback loop maintains continuous updates by processing new games while filtering out low-effort records, preserving both the continuity and precision of ability value and rankings.

Inventive Principle:
Principle #23Feedback

AI summary

An information processing device 10 is an information processing device 10 that is connected to a storage unit 12 that stores records of a player in individual games and is used for calculating an ability value corresponding to valid proficiency of the player. The information processing device 10 includes: a first partial ability value calculation unit 1322 that calculates a first partial ability value based on the records in at least one first game performed in a state where given reliability confirmation processing is not executed; a second partial ability value calculation unit 1323 that calculates a second partial ability value based on the records in at least one second game performed in a state where the given reliability confirmation processing is executed; and a player ability value calculation unit 1324 that calculates an ability value of the player based on the first partial ability value and the second partial ability value.
