As two Manuels recently said, Wikipedia pages are never as precise as you want. Yet, probably, most of Wikipedia accesses actually look for one-line information! (e.g., the birth year of someone) The same for slicing: you may prefer conciseness to soundness, if what you are looking for is only some help in debugging… Thin slicing tries to do this by ignoring some information about the program structure: you may not find the bug, but most of the times you go straight to the point.

I will talk about a PLDI 2007 paper (not mine, sigh) I liked.
