• Development of OQLA: a convex quadratic optimization solver.
• Written in C++,
• Using the augmented Lagrangian approach,
• Can deal with infeasible problems (in that case, it computes the solution to the closest feasible problem),
• The global linear convergence is ensured with a rate given by the user (provided rounding error does not prevail).
  

• Development of MINOQS: a nonlinear differentiable optimization solver using the SQP approach. The code makes use of OQLA as a tool for solving its quadratic subproblems.
