From what I read there are 7 strategies in CLIPS : Depth, Breadth, Simplicity, Complexity, Random, LEX and MEA.
The ones that i have problems with are LEX an MEA. I have read their description on [1], but I did not quite understood them. An example will also be welcomed.

These are strategies used by the OPS5 expert system shell. OPS5 didn't support rule priorities, so these strategies were used to control rule execution using the recency of the facts and in the case of mea the first pattern is given priority. Pretty much the only reason you'd want to use these strategies is to assist in converting an OPS5 program to CLIPS.
