cannot create std::vector larger than max_size() #161

Closed svigerske closed 1 year ago

svigerske commented 1 year ago

When running with Gurobi on lop97ic.gms or lop97icx.gms, there seems to be a problem to get the solution back from Gurobi into SHOT:

[...]
Explored 1937 nodes (46593 simplex iterations) in 0.74 seconds (0.69 work units)
Thread count was 8 (of 8 available processors)

Solution count 10: 4099.06 4122.87 4137.48 ... 4417.51

Optimal solution found (tolerance 1.00e-04)
Best objective 4.099059953600e+03, best bound 4.099059953600e+03, gap 0.0000%

User-callback calls 4455, time in user-callback 0.00 sec
Error when solving problem: cannot create std::vector larger than max_size()

I get this with the current SHOT master, but also versions from half a year ago.

Cannot reproduce this either, SHOT from the command line solves both problems with Gurobi.

What Gurobi version are you using (I am using 9.5.1 build v9.5.1rc2 (linux64))?

9.5.2 build v9.5.2rc0

I don't have access to a system with Gurobi license today, unfortunately.

Seems to be caused by mismatch between Gurobi header and lib on our side (#160), too. Sorry to take your time.
