gana 1.0.4

A barebones mathematical programming package

Gana is an Algebraic Modeling Language (AML) for Multiscale Modeling and Optimization. Generated programs (Prg) can be subclasses of Multiparametric Mixed Integer Linear Programming (mpMILP).

Features

Gana supports:

• mutable elements, allowing constraints/functions to be updated dynamically
• multiparametric as well as mixed integer programming
• formulation in both matrix form and set-based mathematical program

Moreover, Gana uses a simple format to write constraints/functions.

Elements

Programs in Gana are written using element sets, namely:

1. I - index
2. V - variable
3. P - parameter
4. T - parametric variable

Solvers

The list of natively supported solvers are:

1. PPOPT for multiparametric programming (mp)
2. Gurobi for Mixed Integer Programming (MIP) Programs can, however, be exported as a .mps or .lp file and passed to most solvers.

Illustration

Gana is best run in Jupyter as notebook (.ipynb) files, where programs can be visualized as canonical mathematical programs using set-notation.

Additionally, matrices can be exported.

Purpose

Gana was developed to enable certain functionalities in energia (py). Both were developed as PhD projects and have ample room for improvement. So please reach out to me on [e-mail] with suggestions and such.
