SolverPort Instance Feature Dataset

Optimization instance features for meta-learning solver selection across 10 benchmark problem families.

Schema

Each record contains:

instance_id, problem_type, size, seed
features.general — variables, constraints, binary/integer %, sparsity, coefficient range, tightness
features.graph — density, clustering, degree, components, treewidth approximation
features.problem — machines, jobs, capacity utilization, clustering, demand variance, time-window tightness
feature_vector — normalized 18-dim vector for ML models
prediction — recommended solver, config, runtime/gap/feasible estimates

Problem Types

Job Shop, VRP, Facility Location, Bin Packing, Knapsack, Set Cover, Assignment, RCPSP, Network Design, TSP

Usage

from huggingface_hub import hf_hub_download
import json

path = hf_hub_download(
    repo_id="alirezaaminzadeh/solverport-instance-features",
    filename="job_shop_medium_s42_features.json",
    repo_type="dataset",
)
record = json.load(open(path))
print(record["feature_vector"])
