Optimus is a library for Linear and Quadratic mathematical optimization written in [Scala programming language](http://scala-lang.org).
## License
This program comes with ABSOLUTELY NO WARRANTY. This is free software, and you are welcome to redistribute it under certain conditions; See the [GNU Lesser General Public License v3 for more details](http://www.gnu.org/licenses/lgpl-3.0.en.html).
## Features
1. High level mathematical modeling in Scala using algebraic expressions
* Linear and quadratic objective and constraint expressions.
* Higher order expressions cannot be defined or handled by the solvers yet.
* Addition, subtraction and multiplication operations can be performed on expressions.
* Expression simplification produces the simpler form of the expression.
2. Supports various optimization settings by using existing mathematical programming solvers
* Linear programming (LP)
* Quadratic programming (QP)
* Quadratic constraint quadratic programming (QCQP)
* Mixed integer programming (MIP)
3. Available solvers:
* Open source [LpSolve](http://sourceforge.net/projects/lpsolve/) can be used for LP and MIP.
* Open source [oJSolver](http://ojalgo.org/) can be used for LP, QP and MIP.
* Proprietary solver [Gurobi 9](http://www.gurobi.com/) can be used for efficiently solving LP, QP, QCQP and MIP.
* Proprietary solver [Mosek 9](https://www.mosek.com/) can be used for efficiently solving LP, QP, QCQP and MIP.
## How to get Optimus
Optimus is published to Maven Central for Scala 2.12, 2.13 and 3.1.3!
Add the following dependencies to your SBT build file in order to get started:
```scala
libraryDependencies ++= Seq(
"com.github.vagmcs" %% "optimus" % "3.4.3",
"com.github.vagmcs" %% "optimus-solver-oj" % "3.4.3",
"com.github.vagmcs" %% "optimus-solver-lp" % "3.4.3"
)
```
Optionally, you can also add the following extra dependencies for proprietary solvers:
```scala
"com.github.vagmcs" %% "optimus-solver-gurobi" % "3.4.3"
"com.github.vagmcs" %% "optimus-solver-mosek" % "3.4.3"
```
