Sugarscape on Steroids: Simulating over a Million Agents at Interactive Rates
نویسنده
چکیده
In this paper we present a new technique for simulating mega-scale Agent-Based Models (agent population sizes exceeding one million) at interactive rates. We achieve this performance by leveraging the computing power of Graphics Processing Units (GPUs). To test our system, we implemented SugarScape, a simple model with many common ABM features. We are able to achieve over 50 updates per second with agent populations exceeding 2 million on an environment with a resolution of 2560x1024 with visualization.

متن کاملAn Analysis to Wealth Distribution Based on Sugarscape Model in an Artificial Society
In this paper an artificial society is being assumed as a multi agents system. A sugarscape model consisting of a cellular landscape of resources is used to form an interaction among the agents of the population. In the model, agents find the resources to survive. They are supposed to move and search and because of this movement, an evolutionary social behavior will develope. From model analys...

متن کاملThe Effect of Life Expectancy on Risk Aversion
In this paper we investigate the effect of life expectancy on risk attitude in an artificial multi-agent world, which is a variant of the sugarscape [2]. Our basic approach is evolutionary in that we encode risk attitude as a gene within the agents that undergoes variation and selection and perform simulations to see the evolved (i.e., presumed optimal) values of this gene/attitude under differ...

Abstract—Modeling artificial societies that form an economy can add to our understanding of modern economic theory. A case of interest is the Sugarscape model developed by Joshua M. Epstein and Robert Axtell. In many respects, Sugarscape exhibits emergent behaviors that adhere to neoclassical economics; however, other behaviors of the model do not coincide as well with economic theory. We explo...
