A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. 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. http://taustation.com/python3-regex-greedy-and-non-greedy/ graph plotting 3 variablesWebMar 31, 2024 · Greedy Matching 贪婪匹配方法是基于词级别的一种矩阵匹配方法，在给出的两个句子r和r^，每一个词w∈r都会经过词向量转换后变为词向量ew，同时与r^中的每一个词序列w^∈r^的词向量ew^最大程度进行余弦相似度匹配，最后得出的结果是所有词匹配之后的 … graph plotter with lines
