solverarena 0.2.1

A library to run and compare optimization models

Arena Solver

Arena Solver is an open-source library designed to facilitate the performance comparison of different solvers in optimization problems. The library abstracts the implementation of solvers, allowing users to input a list of MPS files and choose the desired solvers with their respective parameters.

Installation

To install the library from PyPI, you can use pipenv with one of the following commands:

1. Basic Installation (only the main library):

   pipenv install arenasolver
   

2. Installation with a Specific Solver:

   If you want to install the library along with a specific solver, you can use:

   pipenv install arenasolver[highs]      # To install with Highs
   pipenv install arenasolver[gurobi]     # To install with Gurobi
   pipenv install arenasolver[scip]       # To install with SCIP
   pipenv install arenasolver[ortools]    # To install with OR-Tools
   

3. Installation with All Solvers:

   If you want to install the library along with all available solvers, use:

   pipenv install arenasolver[all_solvers]
   

Usage

To use the library, you can refer to the example folder, which contains a basic implementation. Here is an example of how to use arena_solver:

from arenasolver.run import run_models

# Define the list of MPS files and solvers
mps_files = ['path/to/model1.mps', 'path/to/model2.mps']
solvers = ['solver1', 'solver2']
parameters = {
    "solver1": {
        "presolve": "on",
        "pdlp_native_termination": True,
        "solver": "pdlp",
    },
}

# Run the models
results = run_models(mps_files, solvers, parameters)
print(results)
