And even though it is somewhat more complicated than the binary system , dna ' s method has worked four billion years Dna的四符号编码方法虽然比二进制编码复杂,但它从诞生到现在已有四十亿年了。
Context - based sign coding is used to remove the redundancy of sign of wavelet coefficient for correlation of them 小波系数的符号间有一定的相关性,使用基于上下文内容的符号编码去除小波系数的符号间的冗余。
Numerical sign coding is improved to solve one - dimensional cutting stock problems . according to this coding we put forward genetic algorithm with elitist model to make new algorithm more effective 针对一维下料问题对符号编码方式作了改进,采用数字符号编码方式,针对订货材料的切割数量不同,提出了相应的遗传算法。
Second , by combining theories of strength of laminate with ga , a new gradient free optimization method with new code strategy is discussed . the representation itself does not change the nature of the problem , but effects the searching efficiency of the algorithm . so the representation of the parameters to be optimized is a very important factor and the new code strategy is also easy used with crossover operator and variation operator in ga applications 其次,本文根据层合板优化设计的具体问题提出了一种符号编码方式,虽然优化参数的基因编码表达方式并不能改变优化问题的本质,但是不同的编码表达方式对于遗传算法搜索的效率和最终的优化结果有着重要的影响,因此优化参数的基因编码表达是遗传算法应用于工程问题中非常关键的一步。
