This paper describes and verifies a convergence model that allows the islands in a parallel genetic algorithm to run at different speeds, and to simulate the effects of communication or machine failure. The model extends on present theory of parallel genetic algorithms and furthermore it provides insight into the design of asynchronous parallel genetic algorithms that work efficiently on volatile and heterogeneous networks, such as cyclestealing applications working over the Internet. The model is adequate for comparing migration parameter settings in terms of convergence and fault tolerance, and a series of experiments show how the convergence is affected by varying the failure rate and the migration topology, migration rate, and migration interval. Experiments conducted show that while very sparse topologies are inefficient and failure-prone, even small increases in topology order result in more robust models with convergence rates that approach the ones found in fullg-connected topologies.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
