A solver based on Column Generation
Project description
Column Generation Solver (Python)
A solver based on column generation.
This is the Python3 version of the C++ package fontanf/columngenerationsolver.
Description
The goal of this repository is to provide a simple framework to quickly implement heuristic algorithms based on column generation.
Algorithms:
- Column Generation
column_generation - Greedy
greedy - Limited Discrepancy Search
limited_discrepancy_search
Examples
Usage, running examples from command line
Install
pip3 install columngenerationsolverpy
Running an example:
mkdir -p data/cuttingstock/instance
python3 -m examples.cuttingstock -a generator -i data/cuttingstock/instance
python3 -m examples.cuttingstock -a column_generation -i data/cuttingstock/instance_10.json
python3 -m examples.cuttingstock -a limited_discrepancy_search -i data/cuttingstock/instance_10.json
Update:
pip3 install --upgrade columngenerationsolverpy
Usage, Python library
See examples.
