<span style="font-family: "Times New Roman", Times, serif; font-size: 16px; color: rgb(13, 13, 13);">I am a Ph.D. student at Worcester Polytechnic Institute (WPI). I recently installed SCIP-Exact 0.3 for my research to solve MIP models without roundoff errors.
Although "</span><span style="font-family: "Times New Roman", Times, serif; font-size: 14px; font-weight: 600;"><code style="font-family: "Times New Roman", Times, serif;">ctest -R MIPEX"</code></span><span style="font-family: "Times New Roman", Times, serif; font-size: 16px; color: rgb(13, 13, 13);">
passed all the tests and confirmed a successful installation, I encountered unexpected behavior while solving a basic knapsack problem. With the exact mode disabled, SCIP provided the optimal solution of 14. However, with the exact mode enabled, SCIP returned
a feasible but non-optimal solution of 0. I tried with a few other examples as well, and in all the examples SCIP returned a non-optimal solution with exact mode enabled. I have attached my model and a screenshot of the SCIP solution for your reference. Could
you kindly provide insights on how to resolve the discrepancy?</span></p>
