Delete elements from a list if they are too close to each other

[Joseph_Oster]

Now that I see your geometry, my suggestion was a waste of time. Serves me right for answering a question without any file(s) attached. Maybe an iterative solution (Anemone)?

P.S. Something similar to this?

Pattern generation with a minimal distance

Do you see how this code works? It proceeds sequentially through the list of rectangles and removes any other rectangles that collide with the one being examined. This means that with the same set of random rectangles (no changes in the white group), you can get a different result by jittering the list sequence (yellow group added) prior to the Anemone loop.
