Software:
- Thyrix is a fast agent/environment
simulator designed for artificial intelligence or artificial life research.
It is optimized for speed, and thus it is very appropriate for evolutionary
experiments. Thyrix allows the simulation of agents with articulated arms
or bodies that interact with objects within a 2D environment with Aristotelian
physics.
