Hi,
I have a branch and price algorithm. In some round, the dual value returned be SCIP is different from another LP solver (CPLEX).
(At the begining of a round, I printed the model and solve it by CPLEX to obtain the dual value.)
Using the dual value provided by CPLEX, I can find some eatra variables, which reduced the lower bound. These varibales cannot
find by dual variables provided by SCIP. So, in my code, I cannot get the real low bound by SCIP.
My computer is 64-bit and the SCIP I used is 32-bit. Is this the reason about my problem ?
best regard,
Kai Wei.
