Multi-agent simulation system

A multi-agent simulation system that performs a simulation of a target world in which a plurality of agents interacting with each other exist,

• the multi-agent simulation system comprising a plurality of computers connected by a network and executing software to implement:
• a plurality of agent simulators configured to perform simulations of the plurality of agents, respectively;
• and
• a center controller configured to communicate with the plurality of agent simulators, wherein
• a subject agent is the agent allocated for each of the plurality of agent simulators,
• the center controller is further configured to deliver at least one delivery message indicating a status of at least one another agent different from the subject agent to the each agent simulator,
• the each agent simulator is configured to:
• determine a status of the subject agent by performing a simulation of the subject agent based on the status of said another agent indicated by the delivery message;
• and
• send a result message indicating the status of the subject agent acquired as a result of the simulation to the center controller,
• the center controller is further configured to deliver the result message received from the each agent simulator as a new delivery message,
• the plurality of agent simulators include:
• a first agent simulator that performs a simulation of a first agent at a first processing time interval;
• and
• a second agent simulator that performs a simulation of a second agent different from the first agent at a second processing time interval longer than the first processing time interval, and
• the center controller is further configured to set a number of a second delivery message delivered to the second agent simulator per unit time to be smaller than a number of a first delivery message delivered to the first agent simulator per unit time, wherein
• the first agent simulator sends a first result message regarding the first agent to the center controller at a first frequency corresponding to the first processing time interval,
• the center controller is configured to select only a part of first result messages received from the first agent simulator as the second delivery message, and to deliver the second delivery message selected to the second agent simulator, and
• the center controller is further configured to select the second delivery message so as to include at least a latest first result message received before a timing at which the second agent simulator determines the status of the second agent.
