The extract function only takes numerals as arguments, not arbitrary expressions. However, we can shift the expression to one direction and then extract the first or last four bits, e.g. along the lines of ((_ extract 11 8) (bvshl l (bvmul idx four))) (where idx and four are bit-vector expressions...

State-of-art sat solver currently uses CDCL(Conflict Drive Clause Learning) based on the DPLL.

so I couldn't get rid of the multiplications without restructuring the whole approach so what I did instead was moving the block with all the conditions (uc=1 or uc=1 and sum = 1) below the forAll block. This worked in most cases but there were still a few tests where...

GLPK, open-source package for LP and (mixed) ILP has Java binding. Another open-source solvers are lp_solve (Java API) and SCIP. There are also commercial solvers - CPLEX, GUROBI and Mosek, all with Java interface. Btw. for my homeworks, I found Python and PuLP a bit easier to work with :)...

The G12/fd solver don't support float decision variables. Do you find G12 MIP solver in the "Solver" list? If so, try it and see if it can solve the model. There is a Help text ("Help, Help...") that might help you add the solver if not. However, if it's an...
