摘要:

“0-1背包问题”是一个经典的组合优化难题,需要从给定集合中选择一个子集。每个物品都具有固有的价值和重量,主要目标是制定一种选择策略,在遵守预定义容量约束的同时最大化总价值。在本文中,我们引入了一种专为解决0-1背包问题(著名的组合优化挑战)定制的Cultural Algorithms(文化算法)新变体。我们提出的算法结合了信念空间来优化种群,并引入了两个关键函数,用于在进化过程中动态调整交叉率和变异率。通过广泛的实验,我们提供了令人信服的证据,证明该算法在持续定位全局最优解方面具有卓越的效率,即使在具有高维度和复杂约束的背包问题中也是如此。

英文摘要:

The "0-1 knapsack problem" stands as a classical combinatorial optimization conundrum, necessitating the selection of a subset of items from a given set. Each item possesses inherent values and weights, and the primary objective is to formulate a selection strategy that maximizes the total value while adhering to a predefined capacity constraint. In this research paper, we introduce a novel variant of Cultural Algorithms tailored specifically for solving 0-1 knapsack problems, a well-known combinatorial optimization challenge. Our proposed algorithm incorporates a belief space to refine the population and introduces two vital functions for dynamically adjusting the crossover and mutation rates during the evolutionary process. Through extensive experimentation, we provide compelling evidence of the algorithm's remarkable efficiency in consistently locating the global optimum, even in knapsack problems characterized by high dimensions and intricate constraints.
