"The high levels of intelligence seen in humans, other primates, certain cetaceans and birds remain a major puzzle for evolutionary biologists, anthropologists and psychologists. It has long been held that social interactions provide the selection pressures necessary for the evolution of advanced cognitive abilities (the ‘social intelligence hypothesis’), and in recent years decision-making in the context of cooperative social interactions has been conjectured to be of particular importance. Here we use an artificial neural network model to show that selection for efficient decision-making in cooperative dilemmas can give rise to selection pressures for greater cognitive abilities, and that intelligent strategies can themselves select for greater intelligence, leading to a Machiavellian arms race. Our results provide mechanistic support for the social intelligence hypothesis, highlight the potential importance of cooperative behaviour in the evolution of intelligence and may help us to explain the distribution of cooperation with intelligence across taxa."
The OSP Collection provides curriculum resources that engage students in physics, computation, and computer modeling. Computational physics and computer modeling provide students with new ways to understand, describe, explain, and predict physical phenomena.
" Cathode, a "vintage terminal emulator" for Mac. It simulates phosphor burn, screen curvature, glare, refresh rates, beam desyncrhonization, jitter, and other effects common to mini-computer terminals of yore."
"This paper develops the concepts and methods of a process we will call ldquoalignment of computational modelsrdquo or ldquodockingrdquo for short. Alignment is needed to determine whether two models can produce the same results, which in turn is the basis for critical experiments and for tests of whether one model can subsume another. We illustrate our concepts and methods using as a target a model of cultural transmission built by Axelrod. For comparison we use the Sugarscape model developed by Epstein and Axtell."

The Johns Hopkins University Center for Advanced Modeling in the Social, Behavioral and Health Sciences is being launched by Joshua M. Epstein. A former senior fellow at the Brookings Institution, Epstein is an internationally recognized pioneer in the field of “agent-based” simulation modeling, which creates virtual worlds populated by “agents” that act like real people.
“With the launch of this center, Johns Hopkins is firmly planting its flag in the ground and saying we are going to be a mecca for groundbreaking research and applied work in the field of agent-based modeling,” said Epstein, who joined the Johns Hopkins faculty July 1 as a professor in the School of Medicine’s Department of Emergency Medicine. He also holds joint appointments in the School of Arts and Sciences’ Department of Economics and the School of Public Health’s departments of Biostatistics and Environmental Health Sciences.
Nomic is a game created in 1982 by philosopher Peter Suber in which the rules of the game include mechanisms for the players to change those rules, usually beginning through a system of democratic voting.
emergentTM (a major rewrite of PDP++) is a comprehensive simulation environment for creating complex, sophisticated models of the brain and cognitive processes using neural network models. These same networks can also be used for all kinds of other more pragmatic tasks, like predicting the stock market or analyzing data.
