OPEN SOURCE LIBRARIES AND TOOLBOXES
CasADi is an open-source tool for nonlinear optimization and algorithmic differentiation. It facilitates rapid — yet efficient — implementation of different methods for numerical optimal control, both in an offline context and for nonlinear model predictive control (NMPC).

qpOASES is an open-source C++ implementation of the recently proposed online active set strategy, which was inspired by important observations from the field of parametric quadratic programming (QP). It has several theoretical features that make it particularly suited for model predictive control (MPC) applications. Further numerical modifications have made qpOASES a reliable QP solver, even when tackling semi-definite, ill-posed or degenerated QP problems. Moreover, several interfaces to third-party software like Matlab or Simulink are provided that make qpOASES easy-to-use even for users without knowledge of C/C++.

Ipopt is an open-source solver for large-scale nonlinear continuous optimization. It can be used from modeling environments, such as AIMMS, AMPL, GAMS, or Matlab, and it is also available as a callable library with interfaces to C++, C, Fortran, Java, and R. Ipopt uses an interior point method, together with a filter linear search procedure.

A toolbox that uses C++ implementations of CasADi, Ipopt, and acados in the backend. Derivatives are calculated automatically using CasADi. For trajectory optimization they use the direct collocation method and solve the non-linear program using CasADi and Ipopt. OpenOCL has a basic interface to acados which provides some fast SQP methods.

The Control Toolbox ('CT'), is a C++ library for modeling, control, estimation, trajectory optimization and model predictive control. The CT is applicable to a broad class of dynamic systems, but features additional tools specially designed for robotics. The library contains several tools to design and evaluate controllers, model dynamical systems and numerically solve optimal control problems.

SNOPT is a general-purpose system for constrained optimization. It minimizes a linear or nonlinear function subject to bounds on the variables and sparse linear or nonlinear constraints. It is suitable for large-scale linear and quadratic programming and for linearly constrained optimization, as well as for general nonlinear programs.
