Memory

Individual Memory

def update_memory(self, env)

This method returns a 20x20 matrix (map_size x map_size). It returns the vision/map of the env explored by individual agent. It aids in exploring the env. It uses get_obs method and masks it to get the vision/map for an agent. The default parameters are explained below.

Parameters:

env (env): environment

get_obs (method): The method returns a 39X39 matrix (map_size*2-1) centered around an individual agent. If communication is allowed between agents, observation for that agent is edited to include vision from other agents

Global Memory

def _update_global_memory(self, env)

This method returns a 20x20 matrix (map_size x map_size). It returns the vision/map of the env explored by the team. It aids agents communicate within the team and explore the env. It implements update_memory method for all individual agents and creates the combined vision/map for a team. The default parameters are explained below.

Parameters:

env (env): environment

get_obs (method): The method returns a 39X39 matrix (map_size*2-1) centered around an individual agent. If communication is allowed between agents, observation for that agent is edited to include vision from other agents
