Potential game for dynamic task allocation in multi-agent system.

Area of Science:

• Artificial Intelligence
• Robotics
• Distributed Systems

Background:

• Dynamic task allocation is crucial for multi-agent systems operating in unpredictable environments.
• Existing methods often struggle with varying workloads and limited agent communication ranges.
• Independent decision-making based on local information presents a significant challenge.

Purpose of the Study:

• To propose a novel distributed multi-agent dynamic task allocation method.
• To address challenges posed by dynamic workloads and constrained agent communication.
• To ensure efficient and near-optimal task allocation through a game-theoretic framework.

Main Methods:

• A potential game-theoretic framework was designed for task allocation.
• A time-variant constrained binary log-linear learning algorithm was developed.
• Agents make independent decisions using local information.

Main Results:

• The proposed method guarantees Nash equilibrium with at least 50% suboptimality.
• The best Nash equilibrium corresponds to the optimal solution.
• Global convergence of the learning algorithm was proven under specific conditions.
• Numerical results demonstrated strong global searching ability and effectiveness.

Conclusions:

• The developed potential game-based framework provides an effective approach for distributed dynamic task allocation.
• The learning algorithm ensures convergence and efficient decision-making for agents.
• The method is well-suited for environments with dynamic task workloads and communication constraints.
