Does anybody know how these 2 solvers, (Oj algorithms) from Java and SCIP for Python, relate to each other performance wise (as in: which one is the fastest), when dealing with a typical MILP (Mixed Integer Linear Programming) problem? On first sight, I can't seem to find anything online that can point me in the right direction, and I'm curious!
Thanks in advance!
The SCIP Optimization Suite is one of the fastest MIP and MINLP solvers available in source code. PySCIPOpt, its interface to Python, might be a bit slower when constructing the model but solving times are still good since it's running the pure SCIP C library in the background.
To be honest, I have no experience with oj! Algorithms and cannot say how good this solver is. Apparently it allows to link to Gurobi or CPLEX, so guess in this case it's mainly a modelling wrapper around those APIs providing high performance.
In the end it comes down to your modelling preferences/requirements and your specific problem instances.
