OSQP Ruby

The OSQP (Operator Splitting Quadratic Program) solver for Ruby

Build Status

Installation

Add this line to your application’s Gemfile:

gem "osqp"

Getting Started

Prep the problem - here’s how it should be setup

p = [[4, 1], [0, 2]]
q = [1, 1]
a = [[1, 1], [1, 0], [0, 1]]
l = [1, 0, 0]
u = [1, 0.7, 0.7]

And solve it

solver = OSQP::Solver.new
solver.solve(p, q, a, l, u, alpha: 1.0)

All of these settings are supported.

Warm start

solver.warm_start(x, y)

Data

Arrays and matrices can be Ruby arrays

[[1, 2, 3], [4, 5, 6]]

Or Numo arrays

Numo::NArray.cast([[1, 2, 3], [4, 5, 6]])

Resources

Credits

This library is modeled after the OSQP Python API.
