求解混合整数规划的嵌入正交杂交的差分进化算法

针对混合整数非线性规划问题中同时含有0-1整数变量和连续变量，采用0-1二进制编码和实数编码的混合编码方案，将布尔逻辑运算中的异或(exclusive or， XOR)算子引入到差分进化的变异算子中,以处理0-1整数变量，将基于正交试验设计的正交杂交算子和差分进化的杂交算子相结合，来增强差分进化算法的系统探索能力。为了验证该算法的性能，测试了一些数值例子，并与其他算法作了比较。数值实验结果表明,提出算法具有良好的稳健性和有效性。

Differential evolution with orthogonal crossover for solving mixed-integer programming

For the mixed-integer nonlinear programming with 0-1 integer variables and continuous variables,a mixed-coding scheme is adopted by mixing 0-1 binary code and real code.The exclusive-or(XOR) operator in the Boolean logical operations is introduced to the mutation operator in differential evolution(DE) for dealing with 0-1 integer variables.The orthogonal crossover operator,which is based on the orthogonal experimental design with two-level orthogonal array and factor analysis,is combined with the crossover ...
