ROAMING OPTIMIZATION: A NEW EVOLUTIONARY TECHNIQUE FOR MULTIMODAL OPTIMIZATION
Rodica Ioana Lung, Dumitru Dumitrescu · 2004
Abstract. A new evolutionary technique for multimodal optimization called Roa-ming technique (RT) is proposed. Multiple optima are detected using subpopulations evolving in isolation. A stability measure is defined for sub-populations by which they are characterized as stable or unstable. Stable subpopulations are considered to contain local optima. An external popula-tion called the archive is used to store the optima detected. After a number of generations the archive contains all local optima. Experimental results prove the efficiency of the algorithm. 1.
