Description:
discreteoptimization 0.3.1
Discrete Optimization
Discrete Optimization is a python library to ease the definition and re-use of discrete optimization problems and solvers.
It has been initially developed in the frame of scikit-decide for scheduling.
The code base starting to be big, the repository has now been splitted in two separate ones.
The library contains a range of existing solvers already implemented such as:
greedy methods
local search (Hill Climber, Simulated Annealing)
metaheuristics (Genetic Algorithms, NSGA)
linear programming
constraint programming
hybrid methods (LNS)
The library also contains implementation of several classic discrete optimization problems:
Travelling Salesman Problem (TSP)
Knapsack Problem (KP)
Vehicle Routing Problem (VRP)
Facility Location Problem (FLP)
Resource Constrained Project Scheduling Problem (RCPSP). Several variants of RCPSP are available
Graph Colouring Problem (GCP)
In addition, the library contains functionalities to enable robust optimization
through different scenario handling mechanisms) and multi-objective optimization
(aggregation of objectives, Pareto optimization, MO post-processing).
Installation
Quick version:
pip install discrete-optimization
