WebThe matching pursuit is an example of a greedy algorithm applied on signal approximation. A greedy algorithm finds the optimal solution to Malfatti's problem of finding three … WebIt's not the shortest possible match, just a short match. Greedy mode tries to find the last possible match, lazy mode the first possible match. But the first possible match is not necessarily the shortest one. Take the input string foobarbaz and the regexp o.*a (greedy) or o.*?a (lazy). The shortest possible match in this input string would be ...
