The API abstraction of a MILP solver that takes in a problem instance as specified using the lp-api model and solves the instance. Implementations of this API convert the model instance to ones for a specific solver, and abstract away as ...

Interface definitions of topology elements and AspectJ aspect definitions for helper methods around performing common operations while working with topology entities.

A generic MILP model representation in Kotlin/Java, which is used as the basis for defining problems in a solver-agnostic fashion. Combined with a solver implementation this model is converted into the equivalent model for a MILP solver.

A Java/FFM interface to the GLPK C API for calling the GLPK Solver (https://www.gnu.org/software/glpk/) from Java/Kotlin.

A Java/FFM interface to the HiGHS C API for calling the HiGHS Solver (https://www.highs.dev) from Java/Kotlin.

A Java/FFM interface to the SCIP C API for calling the SCIP Solver (https://www.scipopt.org) from Java/Kotlin.

The implementation of the LPSolver API which uses the CPLEX Solver (https://www.ibm.com/products/ilog-cplex-optimization-studio) to solve MILP problems.

The implementation of the LPSolver API which uses the GLPK Solver (https://www.gnu.org/software/glpk/) to solve MILP problems.

The implementation of the LPSolver API which uses the Gurobi Solver (https://www.gurobi.com) to solve MILP problems.

The implementation of the LPSolver API which uses the HiGHS Solver (https://www.highs.dev) to solve MILP problems.

A Kotlin/Java API to define MILP problems and provide interfaces to multiple commercial and open-source solvers to solve these problems

Functionality to read/write LP Models to file in various formats.

The implementation of the LPSolver API which uses the MOSEK Solver (https://www.mosek.com) to solve MILP problems.

A Java project to import and operate on network topologies, with some implementations to have the topologies available as an in-memory representation or as a persistent representation in a database.

The implementation of the LPSolver API which uses the ojAlgo Solver (https://www.ojalgo.org) to solve MILP problems.

Implementation of a Topology Provider that stores the necessary topology entities in a PostgreSQL database. Implementation based on Eclipselink JDO ORM and can be adapted to multiple backend databases.

The implementation of the LPSolver API which uses the SCIP Solver (https://www.scipopt.org) to solve MILP problems.

Implementation to import topologies as specified in various external formats. Currently, supports importing from SNDLib (https://sndlib.zib.de).

Notifications are generated via aspects on various topology operations, and handlers can be attached to process these notifications in an asynchronous fashion. This module includes implementations of these notifications handlers.

An in-memory implementation of the topology elements providing a mechanism to import and operate on network topologies in small-scale applications.
