... approach to guarantee specified global behaviors through local coordination and control design for multiagent systems The basic idea is to decompose a requested global specification into subtasks ... how to obtain local tasks from the global task? how to compose them to retrieve the global task? and how to compare the composition of local tasks with the global task? (what equivalent relation ... synchronize on), the global task automaton is defined over the union of all agents’ event sets Consequently, each agent has a local observation from the global task: the perceived global task, filtered...
