摘要: AbstractGenetic algorithms (GAs) can be the tool of choice especially for optimizing combinatorial and complex problems in transport infrastructure systems such as traffic signal control, pavement rehabilitation design, transit service scheduling. This paper presents an overview different techniques to improve performance GAs, with particular emphasis on parallel GAs (PGAs). Results are presented from applications a simple GA (SGA) migration PGAs control problem, benchmark GA–difficult, GA–easy problem. For all problems, savings computation resources were realized when PGA was used. Advantages more pronounced difficult (deceptive) problems. On problem tested this research, four subpopulations 7 times efficient than serial one, eight 18 times efficient. With smaller less impact parallelism is dramatic w...
