Summary
A randomly participating agent in the minority game performs well by recording strategy performance only when participating. This strategy offers a winning edge, even with up to 60% of agents joining randomly.
Area of Science:
- Complex systems
- Game theory
- Agent-based modeling
Background:
- The minority game is a model of strategic decision-making in large populations.
- Agent memory size (m) influences strategy performance in crowded regimes.
- Understanding agent behavior in dynamic environments is crucial.
Purpose of the Study:
- To investigate the performance of a randomly participating agent in the minority game.
- To analyze the impact of selective strategy recording on agent success.
- To explore the relationship between agent inefficiency and success rate.
Main Methods:
- Agent-based simulation of the minority game.
- Analysis of strategy performance based on participation probability (q).
- Characterization of information using 'inefficiency' metric.
Main Results:
- A randomly participating agent with selective recording performs significantly well in crowded regimes (small m).
- The inefficiency metric reveals distinct information patterns for random agents.
- A clear relationship exists between agent success rate and inefficiency, understood through analytical dynamics.
Conclusions:
- Random participation and selective recording is a successful strategy for agents in the minority game.
- The inefficiency measure provides insights into the dynamics of agent strategies.
- The winning edge for random agents persists even with a substantial fraction (up to 60%) of the population participating randomly.
