【Abstract】 While dealing with the problem of synthesis on Process System Engineering (PSE),we often fall into the Conner of multi-peak and singularity, even fail getting their global solution.In this paper, Genetic Algorithms was enhanced by Information Extraction, parallel search and small sampling. The calculation of six standard testing functions of Genetic Algorithms shows us the efficiency of this enhancement. The solution to optimal design of process system and synthesis of heat exchanger networks shows us the robust of this enhancement to mixed integer non-linear problem in synthesis of process system.更多还原
