Detect the formualtion symmetry group of a Mixed-Integer Linear Programming model, the group's orbits and generators are outputs. To do: Mixed-Integer Conic Programming model (linear inequalites should be extended to conic inequalities).

Add and install this package:

pkg.add("https://github.com/lidingxu/SymMIP.jl.git")

Read a JuMP MIP model and analyse its symmetry

using JuMP
using SymMIP
model = model()
#add variables, constraints, and objective
sym_analysis!(model)

Data structures

• sym_analysis : display orbits, and generators of the formulation symmetry group of a transformed model.
