Population structure and particle swarm performance
- …Abstract: The effects of various population topologies on the particle swarm algorithm were systematically investigated. Random graphs were generated to specifications, and their performance on several criteria was compared. What makes a good population structure? We discovered that previous assumpt…

Avoiding the pitfalls of local optima: how topologies can save the day
- …Abstract The problem of premature convergence in the Particle Swarm Optimization (PSO) algorithm is discussed and the importance of the choice of neighborhood to help avoid this problem is demonstrated. A variant of the canonical PSO called Fully Informed Particle Swarm (FIPS) that combines informat…

R.: Neighborhood topologies in fully-informed and best-ofneighborhood particle swarms
- …Abstract: We vary the way an individual in the particle swarm interacts with its neighbors. Performance depends on population topology as well as algorithm version. The particle swarm algorithm is based on a socialpsychological model of social influence and social learning. A population of candidate…

Matching Algorithms to Problems: An Experimental Test of the Particle Swarm and Some Genetic Algorithms on the Multimodal Problem Generator
- …A multimodal problem generator was used to test three versions of genetic algorithm and the binary particle swarm algorithm in a factorial time-series experiment. Specific strengths and weaknesses of the various algorithms were identified. 1. Introduction This paper will compare the performance of…

The fully informed particle swarm: Simpler, maybe better
- …The canonical particle swarm algorithm is a new approach to optimization, drawing inspiration from group behavior and the establishment of social norms. It is gaining popularity, especially because of the speed of convergence and the fact it is easy to use. However, we feel that each individual is n…

Exploiting KeyNote in WebCom: Architecture Neutral Glue for Trust Management
- …A practical trust management system for the WebCom distributed computing architecture is described. KeyNote credentials are used to determine the authorisation of X509 authenticated SSL connections between peers. WebCom provides a meta-language (glue) for bringing together the components of a di…
