From the Hugging Face model README
SolverPort Selection Model
Multi-head meta-model for optimization solver portfolio selection — predicts best solver, configuration, runtime, optimality gap, and feasibility probability from 18 instance features.
Method
Ensemble calibrated scoring (LightGBM / CatBoost / Random Forest / Learning-to-Rank style) with expert-calibrated weights. No training required at inference time.
Heads
| Head | Output |
|---|---|
| Solver rank | Top-1 solver recommendation + full ranking |
| Runtime | Predicted solve time (seconds) |
| Gap | Predicted optimality gap (%) |
| Feasible | Probability of finding feasible solution |
| Config | Auto-tuned solver parameters |
Features (18)
General (7) + Graph (5) + Problem-specific (6) — see instance feature dataset.
Solvers
cp_sat, highs, cbc, scip, glpk, gurobi, minizinc, alns
Tunable Parameters
time_limit_sec, num_search_workers, presolve, cut_strategy, search_branching, heuristic_frequency, neighborhood_size, initial_solution
