Design Rules

Design rules are If-Then rules that depending on the matching degree between observable results and expected results, conclude modifications to be introduced in the parameters that determine the behaviour of agents so that the global behaviour of the system improves relatively to its goal.

Design Rules

In this example...

Given a scenario of buyers and sellers as described before, find some rules that help the user to tune the parameters of the agent Middle to be succesfull in that scenario
