Continuity

Sometime continuing what you started instead of rebuilding from ground is a good thing. Therefore, having LINEAR_CONTINUOUS plots which show the actual continuity of plotting was important. It is now fixed

What's Changed

• Fix a Bug in LINEAR CONTINUOUS control when plotting objectives. by @Ipuch in #457
• checking version for article fix by @Ipuch in #460

Full Changelog: Release_2.2.1...Release_2.2.2

LieDown

To take some rest, you need to lie down. Bioptim does so, by lie on the sheet instead of under, that is getting onto a paper.
This is the official release for the paper (so far)!

What's Changed

• ocp.print() now works with CVODES by @Ipuch in #400
• Pyqt application to run examples by @aceglia in #402
• bug fix when using show_options by @Ipuch in #404
• Add the choice for an integrator of the solution by @Ipuch in #405

Full Changelog: Release_2.1.0...Release_2.1.1

TakeSomeRest

Assessing your fatigue level is important in order to know when to slow down. Bioptim was not able to properly assess it effort level while optimizing. This is now fixed! Using FatiguePerception, bioptim now knows properly how to compute fatigue over time and optimize according to it.

In the mean time, I will focus on my thesis writing, so I also take some rest!

What's Changed

• Multiple Collocation bug fix by @pariterre in #390
• Adding a new Class SolverOptions to manage IPOPT and ACADOS efficiently by @Ipuch in #387
• Symmetry by mapping by @AnaisBellia in #391
• Merged solver and solver options by @pariterre in #395
• Update Quat example + test by @EveCharbie in #396
• Added fatigue perception scaler by @pariterre in #397
• Made fatigue perception limited to 0/1 by @pariterre in #398
• Fixed cost function print when using multi_threads by @pariterre in #399

New Contributors

• @AnaisBellia made their first contribution in #391

Full Changelog: Release_2.0.3...Release_2.1.0

TiredOfWaiting

Are you bored waiting after the optimization? Obviously everyone wants things to go faster! You can now c-compile the function optimized by Ipopt! Also, while you are being fatigued, why not optimizing it with the brand new fatigue model!

Enjoy :D

What's Changed

• phase transition with different nx and nu by @EveCharbie in #372
• Added a cyclic Receding Horizon by @pariterre in #376
• Add Acados real time to optimize and add options in MHE class by @aceglia in #371
• Added a smooth if_else to replace casadi's one by @pariterre in #378
• Modified pendulum examples by @Ipuch in #377
• Added number of CPUs for Acados multiprocessing in installation file. by @aceglia in #386
• CVODES update by @Ipuch in #381
• Implemented the Michaud fatigue by @pariterre in #379

ShowMeWhatYouveGot

The very nature of an optimization, is to be better at something. But bioptim was shy. It would not show you how good it was!
This is no longer the case! Now Bioptim can happily show you its performance on objective function WHILE optimizing!

Now it is your turn to show us what you've got ;)

MyColoc

Bioptim implemented the direct collocations for those who prefer them to direct multishooting!

Symbols

The rewriting of the core opens new doors that did not even exist before. Now, it is possible to plan for integrated objective!
The API was also improve to get a better user experience.
Bioptim gets mature and we hope you will like it

MACADOS

Installing acados into Mac was a mess, now it would be a mess not to! The reason? Installing acados on Mac is now easy as pie! Give it a try
