QuadraticModels

Linux/macOS/Windows: CI FreeBSD: Build Status codecov.io Documentation/stable Documentation/dev

A package to model linear and quadratic optimization problems using the NLPModels.jl data structures.

The problems represented have the form

optimize   c₀ + cᵀ x + ½ xᵀ Q x    subject to   L ≤ Ax ≤ U and ℓ ≤ x ≤ u,

where the square symmetric matrix Q is zero for linear optimization problems.
