动态规划(dynamic programming,DP)和贪心算法(greedy algorithm,GA)的区别是什么? 一、灵感 学习任何算法,最重要的点就是掌握算法的核心本质。本文重点介绍两种经典算法(DP和GA)的差异和相同点。 二、DP和GA的异同点 2.1 、相同点: DP和GA都利用了历史信息进行求解。但是二者利用历史信息的方式有所区别。 2.2 、...
Dynamic programming and Greedy algorithm There is a confusing question, i.e. the name of this method is dynamic programming, how can we understand it ? The dynamic programming in chinese is “动态规划”, to be honest, this translation is imprecise, because we can’t get the real thinking o...
The tools applied in this development are based on the graph theory, generalized approximate dynamical programming method and greedy algorithms. The results are presented on both the fundamental and applied level.doi:10.70594/brain/v10.i1/10Manana Chumburidze...

Greedy Algorithms vs Dynamic Programming Greedy Algorithmsare similar to dynamic programming in the sense that they are both tools for optimization. However, greedy algorithms look for locally optimum solutions or in other words, a greedy choice, in the hopes of finding a global optimum. Hence gree...
A calculus of relations is used to reason about specifications and algorithms for optimisation problems. It is shown how certain greedy algorithms can be seen as refinements of dynamic programming. Throughout, the maximum lateness problem is used as a mo
