Greedy Algorithm 3 Knapsack Problem 3.1 Fractional Knapsack Problem
Greedy algorithm is a group of algorithms that have one common characteristic, making the best choice locally at each step without considering future plans. Thus, the essence of greedy algorithm is a choice function: given a set of options, choose the current best option. Because of the myopic nature of greedy algorithm, it is (as expected) not correct for many problems. However, there are cert...
متن کاملAlgorithms for the Container Loading Problem
In this paper we consider the three-dimensional problem of optimal packing of a container with rectangular pieces. We propose an approximation algorithm based on the "forward state strategy" of dynamic programming. A suitable description of packings is developed for the implementation of the approximation algorithm, and some computational experience is reported. Zusammenfassung: Zur nn aherungs...
متن کاملHeuristics for the container loading problem
The knapsack container loading problem is the problem of loading a subset of rectangular boxes into a rectangular container of fixed dimensions such that the volume of the packed boxes is maximized. A new heuristic based on the wall-building approach is proposed, which decomposes the problem into a number of layers which again are split into a number of strips. The packing of a strip may be for...
متن کاملOn a Stochastic Knapsack Problem
The deterministic knapsack problem is a well known and well studied NP-hard combinatorial optimization problem. It consists in filling a knapsack with items out of a given set such that the weight capacity of the knapsack is respected and the total reward maximized. For a review of references on the stochastic knapsack problem, stochastic gradient algorithms and branch-and-bound methods see [4]...
متن کاملA Tree Search Algorithm for Solving the Container Loading Problem
The paper presents a tree search algorithm for the three-dimensional container loading problem (3D-CLP). The 3D-CLP is the problem of loading a subset of a given set of rectangular boxes into a rectangular container so that the packed volume is maximized. The method has two variants: the packing variant guarantees full support from below for all packed boxes, while this constraint is not taken ...
