Clemens Eisenhofer	6b48b25beb	Draft: Made division/remainder to op_constraints (not yet used - old code still called)	2023-02-09 23:36:15 +01:00
Jakob Rath	b460150f98	tried logic ALL for univariate solver ... Allows us to solve bench25 but some others turn into unknown	2023-01-25 11:42:02 +01:00
Jakob Rath	7fbf27309b	rename	2023-01-25 11:42:02 +01:00
Jakob Rath	26e7d0d35a	We need to use expr_ref when storing expressions across add calls ... Without this, bench3 created a constraint 2^parity == x * parity which should have been 2^parity == x * x_inv.	2023-01-16 15:41:04 +01:00
