Identification of transcription factor b.nding sites from the upstream regions of genes is a highly important and unsolved prob.em. In this paper, we propose a novel framework for using evolutionary algorithm to solve this challenging issue. Under this framework, we use two prevalent evolutionary algorithms: Genetic, Algorithm (GA) and Particle Swarm Optimization (PSO) to find unknown sites in a collection of relatively long intergenic sequences that are suspected of b.ing b.und b. the same factor. This paper represents b.nding sites motif to position weight matrix (PWM) and introduces how to code PWM to genome for GA and how to code it to particle for PSO. We apply these two algorithms to 5 different yeast Saccharomyces Cerevisiae transcription factor b.nding sites and CRP b.nding sites. The results on Saccharomyces Cerevisiae show that it can find the correct b.nding sites motifs, and the result on CRP shows that these two algorithms can achieve more accuracy than MEME and Gib.s Sampler.
