Greedy Algorithms - GeeksforGeeks
2024年7月30日 · A greedy algorithm is a type of optimization algorithm that makes locally optimal choices at each step to find a globally optimal solution. It operates on the principle of “taking the best option now” without considering the long-term consequences.
小白带你学---贪心算法（Greedy Algorithm) - 知乎 - 知乎专栏
贪心算法（Greedy Algorithm) 简介. 贪心算法，又名贪婪法，是寻找 最优解问题 的常用方法，这种方法模式一般将求解过程分成 若干个步骤，但每个步骤都应用贪心原则，选取当前状态下 最好/最优的选择 （局部最有利的选择），并以此希望最后堆叠出的结果也是 ...
Greedy algorithm - Wikipedia
A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. [1] In many problems, a greedy strategy does not produce an optimal solution, but a greedy heuristic can yield locally optimal solutions that approximate a globally optimal solution in a reasonable amount of time.

一、介绍. 在某一个标准下，优先考虑最满足标准的样本，最后考虑不满足标准的样本，最终得到一个答案的算法。. 换言之，在对问题求解时，总是做出 在当前看来最好的选择。. 不从整体最优上考虑全局最优解，而是考虑某种意义上的 局部最优解。. 贪心算法 ...
貪婪演算法 - 維基百科，自由的百科全書
貪婪演算法（英語： greedy algorithm ），又稱貪心演算法，是一種在每一步選擇中都採取在當前狀態下最好或最佳（即最有利）的選擇，從而希望導致結果是最好或最佳的演算法。
Greedy Algorithms | Brilliant Math & Science Wiki
A greedy algorithm is a simple, intuitive algorithm that is used in optimization problems. The algorithm makes the optimal choice at each step as it attempts to find the overall optimal way to solve the entire problem.
Greedy Algorithm - Programiz
A greedy algorithm is an approach for solving a problem by selecting the best option available at the moment. It doesn't worry whether the current best result will bring the overall optimal result. The algorithm never reverses the earlier decision even if the choice is wrong. It works in a top-down approach.
