The knapsack problem is one of the most popular NP-hard problems in combinatorial optimization. For 0-1 Knapsack Problem, there are two common approaches which guarantee the optimality of the solutions: Branch-and-Bound (BnB) and Dynamic Programming (DP) algorithms. Both algorithms suffer from a...
动态规划问题(Dynamic Programming)应该是很多人头疼的一类问题, 本文尝试探索一种套路帮助解决此类问题什么是动态规划?动态规划的核心思想是将问题分解为一系列子问题,并通过记忆化或递推的方式求解子问题,从而得到原始问题的解。动态规划的特点其主要特点包括:...

A novel dynamic programming heuristic for the quadratic knapsack problem 2024, European Journal of Operational Research Citation Excerpt : This section presents the results of running our proposed algorithms on the hidden clique instances. Similarly to the instances in the previous section, we report th...
The types of knapsack that has been discussed so far is only to maximize the use not to exceed the limits specified capacity so it cannot be applied to the problem. This study aims to develop a dynamic programming algorithm to solve the MinMax 0/1 knapsack, which is an extension of the ...
Because the value and size of items and the size of knapsack can change along with the time, it causes that solving this problem is more difficult. We proposed an efficient algorithm for solving RTVKP with dynamic size of knapsack based on dynamic programming method, and analyzed the ...
