I was adding lazy cuts where==GRB_CB_MIPSOL and also adding user cuts where==GRB_CB_MIPNODE. The getNodeRel() was added in GRB_CB_MIPNODE

I made a typo in previous comment. I was using getNodeRel() in GRB_CB_MIPNODE. And get that errors sometimes. Also, the obtained solution is not optimal sometimes. Do you have any idea why this hap...

Thank you for replying! I implemented my project with C++. In the callback that where==GRB_CB_MIPSOL, I obtained the solution with getNodeRel(variable, #of variables). Then I used a constraint to c...
