ACML Speaker: Pierre Guillon ACML is a software written in the Objective Caml language by Guillaume Theyssier (Universite' de Savoie, France), and which is still in beta version. Its goal is to nicely output space-time diagrams of one-dimensional cellular automata, and evolution of two-dimensional ones. The principle is the use of the programming language to fully describe the local rule and options, offering (to those who can manipulate it) a wide flexibility, and possibility to add various plugins. We will see some of the (current) features.
