遗传算法起源于对生物系统所进行的计算机模拟研究。早在本世纪40年代，就有学者开始研究如何利用计算机进行生物模拟的技术，他们从生物学的角度进行了生物的进化过程模拟、遗传过程模拟等研究工作，但由于缺乏一种通用的编码方案，只能依赖变异而非交叉来产生新的基因结构，因而收效甚微。-Genetic algorithms originated in the biological system for the computer simulation. Early in this century, 40 years, some scholars began to study how to use computer simulations of biological technology, from a biological point of view of their biological evolution process simulation, process simulation and other genetic studies, but the lack of a common coding programs rely on variation rather than cross to generate a new gene structure, and thus have little effect.
