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...
The Change-Making Problem is to represent a given value with the fewest coins\nunder a given coin system. As a variation of the knapsack problem, it is known\nto be NP-hard. Nevertheless, in most real money systems, the greedy algorithm\nyields optimal solutions. In this paper, we study...

You mean I will only need to add the condition x<=a[i] to while loop in this code which solve the problem when having inf. coins.Indeed. how stupid my question! Thank you.

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 number of UTXO inputs....
