<div><span></span>Hi,</div><div><br></div><div><span style="font-size: 10.5pt; line-height: 1.5; background-color: window;">I have a branch and price algorithm.</span><span style="font-size: 10.5pt; line-height: 1.5; background-color: window;"> </span>In some round, the dual value returned be SCIP is different from another LP solver (CPLEX).</div><div>(<span style="font-size: 10.5pt; line-height: 1.5; background-color: window;">At the begining of a round, </span><span style="font-size: 10.5pt; line-height: 1.5; background-color: window;">I printed the model and solve it by CPLEX to obtain the dual value.) </span></div><div><br></div><div>Using the dual value provided by CPLEX, I can find some eatra variables, which reduced the lower bound. These varibales cannot </div><div>find by dual variables provided by SCIP. So, in my code, I cannot get the real low bound by SCIP.</div><div> </div><div>My computer is 64-bit and the SCIP I used is 32-bit. Is this the reason about my problem ?</div><div><br></div><div>best regard,</div><div><br></div><div>Kai Wei.</div><div><br></div><div><br></div>
