WebThere 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 a match is WebWhether you are meeting a far away friend, organizing a Craigslist transaction, or connecting with a client for lunch, MeetWays helps you find the halfway point. No more …
