WebJun 2, 2024 · The algorithm simply selects a random set of radii, sorts them into decreasing order (so the larger circles get placed first), and keeps track of where each circle has been placed. In attempting to place the next circle, it selects a uniformly random point within the containing circle as its centre and checks that it will not overlap any other. solo shooting
