Blast bug fix made old proof too slow
paulson [Fri, 16 Feb 2001 13:29:07 +0100] rev 11152
Blast bug fix: now always duplicates when applying a haz rule,
whether or not new variables are added.
Can now prove theorems such as these:
val prems = Goal "[|P==>Q; P==>~Q|] ==> ~P";
by (blast_tac (claset() addDs prems) 1);
val prems = Goal "[|Q==>P; ~Q==>P|] ==> P";
by (blast_tac (claset() addIs prems) 1);
