It doesn't depend on a heuristic approach at all. Shapiro tries to find the faulty part of a bad program by executing part of the program, then asking an "oracle" to decide if that part worked correctly. I am very impressed with Shapiro's work, but it doesn't have anything to do with "expert knowledge." Scott Renner {ihnp4,pur-ee}!uiucdcs!renner
