<div dir="ltr">Dear IPOPT user community,<div><br></div><div>We have just released a new version (v1.9.0) of the free and open-source optimization framework CasADi.</div><div><br></div><div>CasADi allows you to formulate and solve optimization problems, in particular nonlinear programs (NLPs) and optimal control problems (OCPs) using a symbolic, everything-is-a-matrix type syntax. It contains interfaces NLP solvers, in particular IPOPT, which like algebraic modelling languages (AMPL, GAMS) automatically calculates all desired derivative information, including large-scale and sparse Jacobians, Hessians, using state-of-the-art algorithms for algorithmic differentiation. CasADi also supports C-code generation, efficient embedding of ODE/DAE integrators into nonlinear programs, symbolic import of optimal control problems from the Modelica language and many other things.</div>
<div><br></div><div>This release includes a major update of the API in preparation for the first non-beta release which will follow later this year. With this we believe that CasADi should now be more accessible to new users.</div>
