Runtimes dataset for Algorithm Selection on MILP-Evolve and MIPLIB 2017 across 12 Gurobi configurations

Abstract

This dataset provides raw solver runtimes for Mixed-Integer Programming (MIP) instances solved using Gurobi 12.0 with different parameter configurations. Configurations The evaluated portfolio comprises 12 distinct configurations defined as: $$C = \{(p, h) \mid p \in \{0, 1, 2\}, h \in \{0, 0.05, 0.20, 0.60\}\}$$ Presolve ($p$): Controls model reduction and reformulation through redundancy removal, variable fixing, and constraint tightening. 0: Disabled 1: Conservative 2: Aggressive Heuristics ($h$): Controls the fraction of solver time dedicated to finding feasible integer solutions. 0: $0\%$ (Disabled) 0.05: $5\%$ 0.20: $20\%$ 0.60: $60\%$ Dataset files The repository includes the following CSV files: miplib2017.csv Contains raw runtimes for 196 instances from the MIPLIB 2017 benchmark library. Includes columns for all 12 configuration pairs plus a baseline default Gurobi run (grb_default). milp_evolve.csv Contains raw runtimes for instances from the MILP-Evolve dataset evaluated across the 12 parameter configurations. milp_evolve_grbdefault.csv Contains baseline default Gurobi runtimes (grb_default) specifically for the subset of test instances used in the associated paper evaluation. Column naming Instance: Name of the MIP instance file (e.g., .mps file). p{p}_h{h}: Solver runtime (in seconds) under the specific presolve level $p$ and heuristic fraction $h$ (e.g., p0_h0 represents Presolve = 0, Heuristics = 0%; p1_h0.2 represents Presolve = 1, Heuristics = 20%). grb_default: Solver runtime (in seconds) using Gurobi's default parameters.
