Abstract Integrator Error

Hi Dr. Geijtenbeek, Thank you so much for helping me understand SCONE and for your patience with me as I ask you these questions. I was wondering if you could explain this error that I ran into for me: Screenshot 2024-10-29 111918.png I plan to model a passive prosthetic by inputting an estimated pa...

Re: Evaluation Fitness vs. First Generation Fitness

Dr. Geijtenbeek, Sounds good. I will definitely try this method. Could you explain the difference of initializing the parameters with the controller and the .par file? To my current understanding, the optimization would start with the parameters set in the par file, but then use the optimizable para...

Re: Evaluation Fitness vs. First Generation Fitness

Dr. Geijtenbeek, I am not using a .par file to initialize my parameters. Though, now knowing this, I will start doing this from now on. In order to begin doing this, would I have to change my controller at all or would the .par file be replacing my controller? Do I add this par file in the main SCON...

Re: Evaluation Fitness vs. First Generation Fitness

Dr. Geijtenbeek, Thank you for your response. I am now wondering if it would be best to also update the standard deviations as well as the means after every optimization for my purpose. Ultimately, I would like to let my simulations search for more possible solutions after it begins with it's initia...

Evaluation Fitness vs. First Generation Fitness

Hi Dr. Geijtenbeek, I hope you are doing well and thank you for answering my previous inquiries. I was wondering if you would have any advice to begin the optimizations with the fitness that appears in the evaluation results. The first few generations of my optimization are usually a huge factor lar...

Re: Error Running Simulations Even Though Evaluation Completes

Yes! That post helped me out with running simulations with that error.

Thank you,

Dr. Geijtenbeek,

Nevermind! I found the answer in a previous entry.

Thank you!

Error Running Simulations Even Though Evaluation Completes

Hi Dr. Geijtenbeek, I hope you are doing well. I came across this error when I was starting my optimization. Screenshot 2024-10-21 125606.png When I evaluated the simulations, the simulations runs smoothly and completes a simulation with no singularity in the muscles. I have tried bounding my optimi...

Asymmetrical Reflex Control

Hi Dr. Geijtenbeek, I hope you are having a wonderful day. I was curious if there is a way to adjust the "target" and "source" bodies within the Geyer and Herr reflex controller to only act on one side for some of the muscles. I would like to keep symmetry for all of the muscles except for the plant...

Re: Ground Contact at Initial State

Hi Dr. Geijtenbeek,

Thank you for this suggestion. Just to clarify, is this command setting the initial body weight of the model or an additional load that is added on top of the model's weight?

Thank you so much,

Eric
