解法 > 背包问题是关于最佳化的问题,要解最佳化问题可以使用「动态规划」(Dynamic programming),从空集合开始,每增加一个元素就先求出该阶段的最佳解,直到所有的元素加入至集合中,最后得到的就是最佳解。以背包问题为例,我们使用两个阵列value与item,value表示目前的最佳解所得之总价,item表示最后一个放至背包的水...

One of the classical problems of dynamic programming is the 0/1 knapsack problem. The thief has a knapsack of given capacity, and he wishes to maximize the profit with the available valuables. What should he do? Though it would be weird if he starts implementing DP at the crime scene. Bu...

经过小编这几天冒着挂科的风险,日日修炼,终于赶在考试周中又给大家更新了一篇干货文章。关于用变邻域搜索解决0-1背包问题的代码。怎样,大家有没有很感动? 02 什么是0-1背包问题? 0-1 背包问题:给定 n 种物品和一个容量为 C 的背包,物品 i 的重量是w_i,其价值为 v_i。 问:应该如何选择装入背包的物品...
Test runner (testing framework)- each programming language has its own testing framework. For instance, in Ruby programming language there are test runners like RSpec, Cucumber, Minitest. In JavaScript, you can find Jest, Puppeteer, Karma, Jasmine, Cypress, TestCafe, etc. In Python, there...
A parallel implementation via CUDA of the dynamic programming method for the knapsack problem on NVIDIA GPU is presented. A GTX 260 card with 192 cores (1.4 GHz) is used for computational tests and processing times obtained with the parallel code are compared to the sequential one on a CPU ...
