贪心搜索(greedy search): 贪心搜索最为简单,直接选择每个输出的最大概率,直到出现终结符或最大句子长度。 集束搜索(beam search): 集束搜索可以认为是维特比算法的贪心形式,在维特比所有中由于利用动态规划导致当字典较大时效率低,而集束搜索使用beam size参数来限制在每一步保留下来的可能性词的数量。集束搜索是在...
At each step in its search, a greedy algorithm makes the best decision it can at the time and continues without backtracking. For example, an algorithm may perform a general-to-specific search and at each step, commits itself to the specialization that best fits that training data, so far....
3 Greedy algorithm as the heuristic Greedy search algorithm is an effectual tool, which is generally used for optimization problems. The important steps of all greedy algorithms are as follows: 1. Choosing a candidate set and dividing the main problem into a finite set of subproblems. For the ...
贪心算法 基本要素 贪心选择 常见应用场景 贪心算法(英语:greedy algorithm),又称贪婪算法,是一种在每一步选择中都采取在当前状态下最好或最优(即最有利)的选择,也就是说,不从整体最优上加以考虑,他所做出的是在某种意义上的局部最优解。比如在旅行推销员问题中,如果旅行员每次都选择最近的城市,那这就是一种...
A HYBRID DIFFERENTIAL EVOLUTION -ITERATIVE GREEDY SEARCH ALGORITHM FOR CAPACITATED VEHICLE ROUTING PROBLEMThis paper presents a novel and efficient approach to solve the capacitated vehicle routing problem (CVRP) including distance constraints. CVRP is an optimization problem with an objective to determine ...
