Maybe this wasn't the direction you were going, but I was thinking of the distinction between reducible vs. non-reducible loops. Where one (a compiler) can collapse cycles into single nodes. One could assert that certain programs could only be written using a GOTO spaghetti style but I don't think many people would believe that. http://infolab.stanford.edu/~ullman/dragon/w06/lectures/dfa3.pdf Marcus ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College to unsubscribe http://redfish.com/mailman/listinfo/friam_redfish.com archives back to 2003: http://friam.471366.n2.nabble.com/ FRIAM-COMIC http://friam-comic.blogspot.com/ by Dr. Strangelove
