ODYN: An All-Shifted Non-Interior-Point Method for Quadratic Programming in Robotics and AI

Jose Rojas, Aristotelis Papatheodorou, Sergi Martinez +3

We introduce ODYN, a novel all-shifted primal-dual non-interior-point quadratic programming (QP) solver designed to efficiently handle challenging dense and sparse QPs. ODYN combin…
