Here I have MILP model with 1857 rows, 2336 columns and 9792 nonzeros and I run this lp file in a machine in the following platform Intel Core i5-8250U CPU @ 1.60GHz × 8 , 8.00 G RAM, 64 bit Linux 18.04 system. But Gurobi returns no solution and killed the process after a long time.
Is there any option to resolve this issue I mean to get a feasible solution without taking high capacity system? Thanks in advance.
