A Tough Nut for Proof Procedures,
Abstract
It is well known to be impossible to tile with dominoes a checkerboard with two opposite corners deleted. This fact is readily stated in the first order predicate calculus, but the usual proof which involves a parity and counting argument does not readily translate into predicate calculus. It is conjectured that this problem will be very difficult for programmed proof procedures. (Modified author abstract)
