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...
Hence, paper presents a comparative study of the Greedy and dynamic methods. It also gives complexity of each algorithm with respect to time and space requirements. Our experimental results show that the most promising approaches are dynamic programming.Jay Vala...

In this paper, we proposed Dynamic Chunk Allocation based on channel condition using a Modified Greedy Algorithm in SC- FDMA system. Simulation is performed on the uplink direction and it is assumed that channel state information (CSI) of all users are known and have been available at the bas...

对于这种问题,我们有一个denominations set, 看起来似乎Greedy Algorithm会有用,但实际上具体分析就会发现Greedy是不行的。 比如我们的denominators={1, 3, 4, 6},对于C=8来说: Greedy会先找6,6元币值可以来一张,就剩下C'=2, 现在只能找1元币值,两次,一共三张钞票. ...
we present the performance analysis of an experimental study of our distribution in order, to prove again that such systems provides very interesting and promising infrastructures to speed up, at will, several greedy algorithms or applications, especially, the Arabic OCR based on the DTW algorithm....
Then greedy strategy is introduced according to distribution of monitored nodes to make the algorithm more robust to environment changes. A large number of simulation results have proved the effectiveness of this algorithm and showed that the novel algorithm reduces the number of deployed nodes in ...
When the greedy algorithm is used, all SUs prefer to choose the same channel that they believe is the best, leading to an increase in collisions between SUs and a decrease in average reward. The OMC-ALOHA method achieves a throughput close to the DQN and DRQN methods, but receives a ...
