【算法】sliding window algorithm 最近在leetcode上刷题的时候,新学到一个sliding window algorithm。 leetcode原题 解题思路: 1.根据k值,确定窗口的大小; 2.然后从index 1开始挪位; 例子: lower = 2; upper = 3; k = 2 calories = {1,1,0,2,1,0} 时间复杂度: O(
Bin packing problemOptimization algorithmsSquirrel search algorithmBest fit heuristicOperator strategyBin Packing Problem (BPP) is one of the main optimization problems in which a set of items of known sizes should be packed into a minimum number of bins. In which the total size of items?in each...
In the maximum cardinality bin packing problem, we are given m bins of capacity c and n items of weights w i ( i=1,…, n). The objective is to maximize the number of items packed into the m bins without exceeding bin capacities and without splitting items. Several upper bounds are ...
2020ZJCPC---B. Bin Packing Problem 题意: n个物品,第i个物品的容量是 a[i] ,有无限个箱子,每个箱子的容量是 c ,问按照一下两种放法,最少需要几个箱子。第一种:每次都选择最前面的可以放在物品的箱子,若不存在就增加一个箱子。第二种:每次都选择剩余容量最小的且可以容纳物品的箱子,若不存在就增加一...
To improve the efficiency of packing, the BL algorithm is improved to complete the placement of 2D irregular pieces. In addition, reinforcement learning based on Monte-Carlo is applied to improve the search of the packing sequence. The 2D irregular packing problem is summarized firstly in this ...

This online calculator tries to solve an offline two-dimensional (2D) bin packing problem using Maximal Rectangles heuristic algorithm
Too Long; Didn't Read The Colorful Bin Packing Problem (CBPP) presents unique challenges due to color constraints in bin allocation. This article introduces novel heuristics, meta-heuristic algorithms like Variable Neighborhood Search (VNS), and a matheuristic approach to efficiently solve...
one-dimensional bin-packingIn this paper we have proposed two heuristics for the one-dimensional bin-packing problem. One is a hybrid steady-state grouping genetic algorithm, whereas the other is an improved version of Perturbation MBS' heuristic (Fleszar and Hindi in Comput Oper Res 29:821–...
Online bin packing problem has a long history of study. BestFit(BF), FirstFit(FF) and Harmonick algorithm are three heuristic algorithms for online bin packing problems. As members of the Any-Fit family, BF and FF are simple and intuitive algorithms that do not open new bin until an item...
