OscaR-Lib

Compare

  Analyzed about 23 hours ago

OscaR stands for "Scala in OR (Operations Research)". It is a set of tools implemented in Scala to solve Optimization and Operations Research problems. Currently the content of OscaR is: - cp: a package to solve constraint programming problems - cbls: a package to solve problems with ... [More] constraint based local search - linprog: a package to write LP/MIP models with interfaces to glpk, lp_solve, gurobi and cplex - dfo: a package to solve derivative free optimization problems - des: a package to model discrete event simulation problems - visu: a package to build quickly visualizations for your optimization problem [Less]

OptaPlanner

Compare

  Analyzed almost 2 years ago

OptaPlanner optimizes business resource usage. Every organization faces planning problems: provide products or services with a limited set of constrained resources (employees, assets, time and money). OptaPlanner optimizes such planning to do more business with less resources. OptaPlanner is a ... [More] lightweight, embeddable planning engine written in Java™. It helps normal Java™ programmers solve constraint satisfaction problems efficiently. Under the hood, it combines optimization heuristics and metaheuristics with very efficient score calculation. OptaPlanner is open source software, released under the Apache Software License. It is 100% pure Java™, runs on any JVM and is available in the Maven Central Repository too. [Less]

METSlib Optimization Framework

Compare

  Analyzed almost 3 years ago

METSlib is an OO (Object Oriented) metaheuristics framework in C++. Model and algorithms are modular: all the implemented search algorithms can be applied to the same model and personalized algorithms can be applied to very different models. METSlib implements the basics of some metaheuristics ... [More] algorithm: Random Restart Local Search, Variable Neighborhood Search, Iterated Local Search, Simulated Annealing (with linear, exponential and custom cooling schedule), and last but not least Tabu Search.

MOEA Framework

Compare

  Analyzed about 10 hours ago

The MOEA Framework is an open source Java library for developing and experimenting with multiobjective evolutionary algorithms (MOEAs) and other general-purpose optimization algorithms and metaheuristics. A number of algorithms are provided out-of-the-box, including NSGA-II, ε-MOEA, GDE3 and MOEA/D. ... [More] In addition, third-party tools like JMetal and PISA directly integrate with the MOEA Framework. The MOEA Framework targets an academic audience, providing the resources necessary to rapidly design, develop, execute and statistically test optimization algorithms. This includes over 40 test problems from the literature, and a suite of statistical tools for comparing and analyzing algorithm performance. [Less]

Coin-OR Open Solver Interface (OSI)

Compare

  Analyzed 8 months ago

Osi (Open Solver Interface) provides an abstract base class to a generic linear programming (LP) solver, along with derived classes for specific solvers. Many applications may be able to use the Osi to insulate themselves from a specific LP solver. Provides interfaces for a number of open-source and commercial solvers.
