Introduction

QuadProgMm is a C++ library providing a domain specific language to express Quadratic programming problems as literal C++ equations on named variables.

These problems are generally specified using matrices and vectors, because it is the generic mathematical form used by resolution algorithms. This is sometime tedius, and QuadProgMm tries to fix that.

Note that QuadProgMm does not implement the arguably complex linear algebra algorithms for solving these problems and delegates all that hard work to QuadProg++, by Luca Di Gaspero.

Quick start

Clone and build:

$ git clone https://github.com/jacquev6/QuadProgMm.git
$ cd QuadProgMm
$ make lib

Start with Includes:

#include <iostream>
#include <QuadProgMm.hpp>

using namespace QuadProgMm;

int main() {

Create variables:

Variable a, b, c;

And a quadratic expression to optimize:

QuadraticExpression q = a + b + (a - b) * (a - b) + c + (b - c) * (b - c);

And constraints:

std::vector<Constraint> constraints {
  a <= 1,
  c >= 4,
  a - 2 * b <= 12,
};

Finally, solve:

  Solution solution = minimize(q, constraints);

  std::cout << "a: " << solution.get(a) << std::endl;
  std::cout << "b: " << solution.get(b) << std::endl;
  std::cout << "c: " << solution.get(c) << std::endl;
  std::cout << "Cost: " << solution.getCost() << std::endl;
}

Build and run:

$ g++ -Ipath/to/QuadProgMm/src quick_start.cpp path/to/QuadProgMm/build/libquadprogmm.a path/to/QuadProgMm/QuadProgpp/src/libquadprog.a -o quick_start
$ ./quick_start

Result:

a: 1
b: 2
c: 4
Cost: 16
