Description
Describe the bug
The logs determine the solution is infeasible but status returned is Optimal
cuOpt version: 25.10.0, git hash: e40349f, host arch: x86_64, device archs: 80-real
CPU: AMD EPYC 7642 48-Core Processor, threads (physical/logical): 96/96, RAM: 169.08 GiB
CUDA 12.9, device: NVIDIA A100 80GB PCIe (ID 0), VRAM: 79.33 GiB
CUDA device UUID: 68ffffffdf5cfffffff5-71fffffff9-6aff
Unpresolved problem: 4 constraints, 3 variables, 9 nonzeros
Calling Papilo presolver
Presolve status: reduced the problem
Presolve removed: 4 constraints, 3 variables, 9 nonzeros
Presolved problem: 0 constraints, 0 variables, 0 nonzeros
Papilo presolve time: 0.032460
Best feasible: -3.000000
Post-solve status: Post solved solution violates constraints. This is most likely due to different tolerances.
The solution is not feasible after post solve
Solution objective: -3.000000 , relative_mip_gap 0.000000 solution_bound -3.000000 presolve_time 0.032460 total_solve_time 0.000000 max constraint violation 1.000000 max int violation 0.000000 max var bounds violation 0.000000 nodes 0 simplex_iterations 0
