高效求解多峰值全局优化的区间-遗传算法

针对传统区间优化算法求解高维问题耗时的缺点,将区间算法和遗传算法进行融合,提出了一种区间-遗传算法。该算法利用区间算法为遗传算法的搜索区域进行定界,同时采用拒绝指标可使包含全局最优解的区间更容易被选择,而且算法通过遗传算法提供的问题全局最优解的上界可对那些不包含全局最优解的区间进行删除。对一些多峰值全局优化问题进行了仿真实验,结果表明:该算法相比传统区间优化算法更加有效,而且随着问题维数的增大,算法的高效性更加明显。

Efficient interval-genetic algorithm for multi-peak global optimization

To overcome the disadvantage of high computation cost in traditional interval optimization algorithms for high dimensional problems,an interval-genetic algorithm was proposed.This algorithm combines the interval algorithm and a genetic algorithm.It employed the interval algorithm to bound the search domains of the genetic algorithm,and adopted a reject index to make the intervals containing the global optimum being more easily selected.Moreover,the algorithm used an upper bound of the global optimum provide...
