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 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,
• wherein the center controller comprises one or more processors and a memory storing instructions that implement a movement message dispatcher that relays the communication of the movement messages between all of the plurality of the agent simulators, a plurality of message filters respectively corresponding to the plurality of agent simulators and retaining reference information REF1 regarding processing time intervals of the plurality of agent simulators, a plurality of receive queues and a plurality of send queues, and a forwarder that forwards necessary ones among the result messages stored in each receive queue to necessary send queues, and the center controller retains reference information REF2 including spatial configuration information of the simulation target world and functional information that indicates a correspondence relationship between a distance and a delivery frequency,
• each agent simulator includes a send/receive controller and a 3D physics engine, the 3D physics engine including a surrounding agent status updater that estimates the current status of the surrounding agent existing around the subject agent based on the movement message, and a subject agent status updater that outputs the movement message including the updated status of the subject agent;
• 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 each of the plurality of agent simulators,
• 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,
• a plurality of operation modes of the center controller include:
• a first operation mode that delivers the result message received from each of the plurality of agent simulators as a new delivery message without filtering;
• and
• a second operation mode that selectively delivers the result message received from each of the plurality of agent simulators as a new delivery message,
• when a number of result messages that the center controller receives per unit time is equal to or less than a threshold, the center controller selects the first operation mode, and
• when the number of result messages that the center controller receives per unit time exceeds the threshold, the center controller selects the second operation mode.
