Octopus is a plug-in for applying evolutionary principles to parametric design and problem solving. It allows the search for many goals at once, producing a range of optimized trade-off solutions between the extremes of each goal.
Also see octopus.E for custom evolutionary algorithms.

Octopus introduces multiple fitness values to the optimization. The best trade-offs between those objectives are searched, producing a set of possible optimum solutions that ideally reach from one extreme trade-off to the other.

I have a pretty complex code that’s making an urban planning system to construct blocks and tiles. I made a loop with anemone as I can’t seem to make the Octopus loop work at all (it only does the first stage of the loop and keeps copying it over and over instead of moving forward: which works perfectly with Anemone)
The problem is that when I use Galapagos to run it, the Galapagos listener keeps catching the loop while it is still working, snapping that picture of the viewport, and moves on to change sliders - all before the loop even finished its work.
Any way to make it work? Or an explanation about how the Octopus Loop is different?

Using a complicated loop with Galapagos/Octopus

Hi!
I have a pretty complex code that’s making an urban planning system to construct blocks and tiles.
I made a loop with anemone as I can’t seem to make the Octopus loop work at all (it only does the first stage of the loop and keeps copying it over and over instead of moving forward: which works perfectly with Anemone)
The problem is that when I use Galapagos to run it, the Galapagos listener keeps catching the loop while it is still working, snapping that picture of the viewport, and moves on to change sliders - all before the loop even finished its work.
Any way to make it work? Or an explanation about how the Octopus Loop is different?
It would be very much appreciated!
