We study the effects of mobility on the evolution of cooperation among mobile players, which play prisoner's dilemma games with neighbors within a prescribed radius. We define the reputation as the times one cooperates in past times. We show that reputation-based partner choice promotes cooperation, when compared with the case that partners are chosen at random. And for large values of the velocity,...
In this paper, a dynamical system model has been proposed and a new approach for analyzing homeostasis and evaluating potential systemic toxicity in a living biological system has been developed for nanotoxicology study. Based on the model and approach, the toxicity of 30 nm-sized Fe3O4 nanoparticles was investigated and explained. Experiment results verify feasibility and effectiveness of the dynamical...
Accurate forecast is the key for sales decision-making of tobacco commercial companies. Model selection plays an important role in sales forecast. This paper adopts expert system theory to model selection. Model knowledge tree is set up by selection rules to make knowledge structured and systematic. On the basic of model selection knowledge tree, build up model selection reasoning machine adopting...
According to characteristics of simulation grid resources (SGR), an extend Web service description language (WSDL) was adopted to describe the attributes of SGRs, in order to facilitate the application of machine learning algorithms for SGR scheduling on a centralized-distributed SGR management model. By analyzing the specific requirements of distributed interactive simulation (DIS) task, a SGR scheduling...
