qpSWIFT

Light-weight sparse Quadratic Programming Solver

Introduction

qpSWIFT is light-weight sparse Quadratic Programming solver targetted for embedded and robotic applications. It employs Primal-Dual Interioir Point method with Mehrotra Predictor corrector step and Nesterov Todd scaling. For solving the linear system of equations, sparse LDL' factorization is used along with approximate minimum degree heuristic to minimize fill-in of the factorizations
