作为一个跨到供应链管理顺便学了点ml皮毛的生物狗,想从小白的视角以简单的背包问题(knapsack problem)引入,让各位对于遗传算法有个直观的印象。 背包问题:有5件物品可选,每件物品的价值和体积如表所示。背包的容积为10,怎么样选取物品使总价值最大? 1. Obtain a population of parents 在所有可行的选取组合先随...

Knapsack is an optimization problem. To solve the knapsack problem we used two algorithms and their results were compared. To solve the knapsack problem we use genetic algorithm operators as selection, crossover, and mutation after that we perform the hybridization of GA and the results of both ...

Knapsack problemglobal optimizationIn this study, human reproduction mode was introduced into genetic algorithm and an improved adaptive genetic algorithm based on human reproduction mode for solving 0/1 knapsack problem was presented. The genetic operators of this algorithm included selection operator, ...

In doing so, the algorithm is able to maintain population diversity effectively, which alleviates the risk of premature convergence. Second, SW-MopGA proposes a two-step framework: Initially, the population undergoes evolution on a simplified version of the originally complex problem. Solutions ...
Computational results also show that the genetic algorithm heuristic gives superior quality solutions to a number of other heuristics. 展开 关键词: Theoretical or Mathematical/ genetic algorithms heuristic programming operations research/ heuristic genetic algorithms multidimensional knapsack problem genetic ...
The problem:There are things with given value and size. The knapsack has given capacity. Select things to maximize the value of things in knapsack, but do not extend knapsack capacity. Encoding:Each bit says, if the corresponding thing is in knapsack. ...
