MINLPTests.jl

This is a collection of JuMP models for testing nonlinear/polynomial solvers with and without discrete variables in JuMP.

This version is compatible with the current release of JuMP (using MathOptInterface).

• The tests are organized into broad categories based on the scope of typical (e.g. continuous, convex functions, polynomial, ...)
• Unit tests for JuMP integration testing should be "easy" models. For example, it should be possible for a non-global solver to find the global solution in these tests
• Mathematical property tests can be more difficult but should strive to be as simple as possible

Directories:

• nlp - nonconvex NLP models
