Support & Troubleshooting

What are the system requirements for JOpt?

JOpt doesn’t have fixed “hard” requirements — compute needs depend on the size/complexity of your problem.
Smaller problems (≈20 nodes) can run on very modest hardware, while larger constraint-heavy instances typically benefit from medium to high-performance infrastructure.
