WebJul 22, 2024 · I am currently using JuMP with the Gurobi Solver to optimise a tournament schedule. I use a local search heuristic to try and solve each round in a given time limit after having found a first feasible solution. The problem I now face is, that it takes quite a while to find a first initial solution. Therefore my time limit is quite high. I would like to lower it … WebApr 4, 2024 · Solving exactly same lp problem using XPress api is way faster than using JuMP/MOI: 2 ses vs 9 secs for a simple case; then 452 secs vs 1796 for more complex case.
