Analytic solutions are overrated, y'all😇

@PPuchaud @EveCharbie Thanks for the nice words, but sometimes studying the equations does pay off sciencedirect.com/science/articl…

They love equations so much that one of the presenters even said automatic differentiation doesn’t work. @EveCharbie and I had conversation trying to convince a Spanish researcher of all the benefits of @casadi_software . Guys, come on, it saves so much time !

I’ve been to multibody 2023, @ECCOMASofficial . As a #biomechanist, that is use to go to #biomechanics conference, Here is what surprised me over the past 5 days.

@ChelseaParlett Long live nonlinear programming😁

No, NLP cannot stand for the “Negative Log Posterior”, it’s already got a meaning in this field 😰

@PPuchaud @TimSalzmann Optimal control/model predictive control with a learned system model, for example. There have been several couplings like this with TensorFlow and PyTorch before, but this is the first implementation that supports code-generation and therefore is potentially overhead-free.

@casadi_software Could you elaborate on the perspectives of this. Which feature it would potentially unlock ? @TimSalzmann

CasADi demo youtu.be/5Fpi_C0w2lg - feel like deep-diving in a hands-on workshop? Early bird registrations for ocp2023.casadi.org are still open for two weeks.

CasADi training is back; more info at casadi.org/ocp2023/

We propose a computationally-efficient Convex Lie Algebraic MPC for marine vehicles. The higher water density leads to significant environmental forces and state-dependent vehicle models. The proposed MPC significantly reduces computation time, enabling real-time implementation with longer planning horizons. Paper: arxiv.org/abs/2305.09009 Code: github.com/UMich-CURLY/Li…

FMI 3.0 and 2.0 added in @casadi_software - FMI export is currently FMI 3.0 - FMI import is currenlty FMI 2.0

CasADi 3.6.0 is here! Now compatible with new versions of #Python/#Octave/#Matlab & M1 hardware. New solvers: SPRAL, HPIPM, ProxQP & HiGHS. #FMI/#Modelica interoperability, improvements to ODE/DAE integrators, NLP solvers & symbolics. Details at install.casadi.org

With Real-time Neural MPC you can efficiently integrate large, complex neural network architectures as dynamics models in an MPC-pipeline. Compared to prior implementations we can leverage neural networks with a 4000x larger parametric capacity in a 50Hz real-time framework.

@TonyPlaysGuitar Let's say there is still ample room for improvement😁

@casadi_software ...but does it know how to add a hessian to a custom callback? 🤔

ChatGPT by OpenAI can write meaningful CasADi code

Check out our ongoing research: lightweight, model based, optimal trajectory planning for autonomous vehicles powered by #Rockit and #CasADi (@casadi_software) applied to drone racing for our paper at #AMC2022: ieeexplore.ieee.org/document/97292… #autonomousvehicles #uav #drones #control

@mrpibudd A lot of activity in development branch. 3.6 releases will come by this summer..

First set of simulations: takes ~10 months to converge w/ good results Second set of simulations on new data: takes ~12 hours to converge w/ great results on a first pass. Call me the CasADI master now. I'm taking that as a win!! @JohnRHutchinson #DAWNDINOS
