Black-box expressions Constraint Programming (CP) is known for its expressiveness for modeling and solving combinatorial optimization problems. In particular, CP uses predefined expressions, such as product or division between variables ( x*y*z , x/y ), logarithm ( log(x) ), power ( x^y ),...
A new parameter emphasis mip 5 allows to find solutions 1.8x faster with CPLEX 20.1 . CPLEX has been developed for 30+ years with one performance objective: be as fast as possible to prove the optimality of the best solution that it can find for the model. In other words, the goal is not...
