Flan is a network simulator written in Java. It is meant to be easily expandable by adding new protocols, which are also written in Java. It includes a graphical network construction interface, a RIPv2 (with subnets, that is) protocol, IP packets handling, etc. Flan is based on a continuous time-discrete event simulation engine (with real-time sync).
The RoboCup Soccer Simulator is a platform for evaluating multiple autonomous intelligent agents in a realworld-like domain. The simulator allows two teams of 11 players and one coach to interact in a simulated game of soccer. The team members connect to the simulator using UDP sockets and must perform complex behaviors using only a few basic commands, primarily dash, kick, turn, and catch, based on noisy and infrequent sensor information provided by the simulator. This simulator is used in the simulation league of the RoboCup competition.
The Python lambda calculus module allows simple experimentation with the lambda calculus, which was first developed by Church. It understands the different types of lambda expressions, can extract lists of variables (both free and bound) and subterms, and can simplify complicated expressions by means of application.
The VP7 Way Kool Project is a GTK application which simulates a laboratory experiment with radioactive nuclei. The user can choose between many predefined radioactive sources or create new ones. The number of decayed nuclei and the activity of the source can be determined with a built-in counter. The beam can be attenuated with shields of paper, aluminium, and/or lead.
