Act-RBot a cognitive social simulation tool
ACT-RBOT is a cognitive agent based social simulation toolkit (RBOT+MRS) / production system based on ACT-R (http://act-r.psy.cmu.edu) allows for modelling single actor cognitive experiments (RBOT) and multiple actors in a simulated (semiotic) world (RBOT + MRS). It is still in development and needs more adjustment for especially social simulations with large numbers of agents.
