    Weak equivalence is a relationship between the outputs of two systems that are being compared. If these systems are only weakly equivalent, then we can say that they are computing the same function (or generating the same external behavior), but that they are using different procedures to do so. For example, human chess players and computer chess players are weakly equivalent, in the sense that they both play the game of chess, but use very different procedures to decide which move to make next in a game. (Computer chess players usually use some form of intensive search, which is beyond the memory capacity of human players. Indeed, an interesting question is how humans can play chess so well given that they do not use brute force search methods!)

    Strong equivalence is a stronger condition for model validation than is weak equivalence. If two systems are strongly equivalent then 1) they compute the same function (i.e., they are weakly equivalent), 2) they use the same program to compute this function, and 3) this program is written in the same programming language (i.e., the two systems have the same functional architecture.)
