Expected Performance and Worst Case Scenario Analysis of the Divide-and-Conquer Method for the 0-1 Knapsack Problem
摘要:
在本文中,我们提供质量证书的分治方法解决0-1背包问题:最坏的情况下,预期的性能估计。给出了概率设置,并定义了主要随机变量,用于分析预期性能。效率是严格近似的方法的一次迭代,然后,这些值被用来推导出一般的分治树的性能的分析估计。所有的理论结果进行了验证与统计上合适的数值实验更广泛的说明的方法。
英文摘要:
In this paper we furnish quality certificates for the Divide-and-Conquer method solving the 0-1 Knapsack Problem: the worst case scenario and estimates for the expected performance. The probabilistic setting is given and the main random variables are defined for the analysis of the expected performance. The efficiency is rigorously approximated for one iteration of the method then, these values are used to derive analytic estimates for the performance of a general Divide-and-Conquer tree. All the theoretical results are verified with statistically suited numerical experiments for a wider illustration of the method.
