Nowadays, many artificial life research areas resort to agent-based simulation. This fact has brought us to design a powerful generic platform that would allow scientists in those fields of research to easily build simulation environment. This platform, called MUTANT, includes a model of self-adaptive agent, with genetic evolving capabilities as learning mechanisms. The platform also includes a powerful graphical user interface providing many tools for both modeling and simulation. There are tools for agent1s design, behavior1s programming, environment1s description, and observation of running simulations. MUTANT is being developed in Java with the aim of being directly usable throughout the Internet.
