A basic computer-coded Echo Model that can be applied to a wide range of real-world scenarios as possible This is a python program. You can directly run the "echo.py", and you will see the process of agents evolution.

1. 'agent.py' is a class of the adaptive agent, which define the features and the interactive methods.

2. 'echo_model.py' define the interactions between the agents, we only realizes resource exchange between agents according to the sequence matching.

3. We retain three features: (1) the simple string-specified structure (2) reproduction limited by resource acquisition(implicit fitness) (3) interaction mediated by tags
