"WebMatching Algorithms There are basically two types of matching algorithms. One is an optimal match algorithm and the other is a greedy match algorithm. A greedy algorithm is frequently used to match cases to controls in observational studies. In a greedy algorithm, a set of X Cases is matched to a set of Y Controls in a set of X decisions. Once ...
