Kangaroo results!

[khaled_habach]

Dear experts,

I’m trying to optimize a new definition and I’m using Kangaroo physics in addition to a couple more plugins.
My question is simple, is there a way to get only the last results of the kangaroo solver without having to go through all steps of simulation? this would help a lot with optimization since i’m taking the results from the solver and the parameters are connected to the solver already, any change in the input would cause a huge delay.
Not sure if it’s possible, but this is the best place to ask!

Thanks in advance,
Kal

You can use the zombie solver for optimization problems.
If you use Wallacaei they have an example file using kangaroo.

Yes, as @danielbent says, the Zombie solver is what you are looking for here. There’s a link to an example in this thread:

Optimization with a Kangaroo2 solver

Hi Philip. This is where the ‘ZombieSolver’ component is useful. Instead of showing the iterations live, this just solves the system internally, and outputs the result when either an energy threshold or maximum iteration count has been reached. This makes it behave like a standard grasshopper component in the graph, not needing to be reset, and only updating the output once for each time the input is updated, allowing it to be used inside other optimization loops such as those created with Oct…

Thanks a lot! this is exactly what I was looking for.

Kal,
