测试常见算法面试题:贪心法--找零问题 贪心算法(Greedy Algorithm): 贪心算法是一种基于局部最优选择来构建全局最优解的算法。它通常适用于那些可以通过一系列局部最优选择来达到全局最优解的问题。贪心算法每一步都会做出当前看起来最佳的选择,而不考虑未来的后果是否最优。经典的贪心算法包括霍夫曼编码、最小生成树...
We show how the availability of the greedy algorithm for finding the minimun number of coins in the money exchange problem is related to the Cohen–Macaulay property of the toric projective curves given by the coin values. *Partially supported by junta de Castilla y León VA 27/98 and DGES ...
i.e., a positive integer x such that the minimum number of coins required to dispense exactly x is less than the number of coins used by the greedy algorithm.

Subtask 2: Genetic Algorithm Implement a single objective genetic algorithm for the NRP problem. The objective is to maximize the sum of values of the chosen items, while staying below the given budget constraint. Name your solver assingle_ga.py ...
as do the coin systems used in most countries. The greedy algorithm involves repeatedly choosing a coin of the largest denomination that is less than or equal to the amount still owed, until the amount owed reaches zero. A coin system for which the greedy algorithm is always optimal is calle...

This paper proposes a method based on the greedy and genetic algorithm for effectively choosing sets of UTXOs in Bitcoin. The main objective of this coin selection strategy is to get as close as possible to the target while also maintaining and possibly reducing the nu...
