Multiobjective Discrete Optimization Framework in Julia
Modof.jl
is a framework used for solving multiobjective mixed integer programs in Julia. It has functions for
Selecting, sorting, writing and normalizing a nondominated frontier
Computing ideal and nadir points of a nondominated frontier
Computing the closest and the farthest point from the ideal and the nadir points respectively.
Computing the quality of a nondominated frontier: exact (for biobjective and triobjective) and approximate (for more than 4 objectives) hypervolumes; cardinality; maximum and average coverage; uniformity
Plotting nondominated frontiers of: 1) biobjective discrete and mixed problems and 2) triobjective discrete problems
Wrappers for the following algorithms in linux: 1) MDLS for solving multidimensional knapsack and biobjective set packing problems and 2) NSGA-II for solving biobjective binary programs
Note: Functionalities corresponding to computing quality of a nondominated frontier and plotting nondominated frontiers have been moved to pyModofSup.jl

Installation
Once, Julia v0.6.0 has been properly installed, the following instructions in a Julia terminal will install Modof.jl on the local machine:
Pkg.clone("https://github.com/aritrasep/Modof.jl")
Pkg.build("Modof")
In case Pkg.build("Modof")
gives you an error on Linux, you may need to install the GMP library headers. For example, on Ubuntu/Debian and similar, give the following command from a terminal:
$ sudo apt-get install libgmp-dev
After that, restart the installation of the package with:
Pkg.build("Modof")
