LUXE is an agent-based model of land-market interactions, which allows the user to explore the effects of land market elements (preferences, budget constraints, and competitive bidding) on patterns of land-use and land-value in an abstract urban setting.

#k@ (hashKAT)

#k@ ( is a dynamical network simulation tool designed to model the growth of and information propagation within an online social network. It is an agent-based, kinetic Monte Carlo engine capable of simulating online networks such as Facebook, Twitter, LinkedIn, etc. It incorporates all elements of online social networks including multiple user profiles (e.g. standard users, organizations, celebrities, and bots), user messaging, trending topics, and advertising. Free Software (GPLv3) available for Mac OS X and GNU/Linux.


This software program is designed to help people understand and resolve conflicts. It is based on the hope that increasing empathy (mutual understanding of values and emotions) between people can help to overcome impasses in disputes in many domains: organizations, politics, personal relationships, and so on. EMPATHICA uses the idea of Cognitive-Affective Maps (CAMs) developed by Paul Thagard in collaboration with Thomas Homer-Dixon, Scott Findlay, and others.
