MINLPTests.jl

master: Build Status

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). Past versions are compatable with previous releases of JuMP (using MathProgBase).

Test Design Guidelines

  • The tests are organized into broad categories based on the scope of typical solvers (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

Test Naming Conventions

Directories:

  • nlp - nonconvex NLP models
  • nlp-cvx - convex NLP models
  • nlp-mi - nonconvex MINLP models
  • nlp-mi-cvx - convex MINLP models
  • poly - nonconvex polynomial models
  • poly-cvx - convex polynomial models
  • poly-mi - nonconvex polynomial models
  • poly-mi-cvx - convex polynomial models

File Names:

  • 0xx_yyz - unit tests
  • 1xx_yyz - 2D mathematical properties
  • 2xx_yyz - 3D mathematical properties
  • 5xx_yyz - nD mathematical properties
  • 9xx_yyz - integration tests

z indicates a variant of a base problem
