Jakob Rath	0d56edb65c	Fix missing boolean propagation after boolean conflict ... Usually in SAT solving, the conflict clause has at least two false literals at the max level (otherwise, the last literal would have been propagated at an earlier level). But here we are adding clauses on demand; so after backtracking we may have the case that the conflict clause has exactly one undefined literal that must be propagated explicitly.	2023-02-01 15:02:56 +01:00
