I don't know that a randomized algorithm would be preferable for this problem, since the algorithm implemented here seems to work pretty well as it is. But if the two problems are very similar, factoring out the implementation might be a good idea. In any case, this shouldn't prevent this PR from being integrated, as it also includes tests for the desired outcome. These will come in handy if the implementation is refactored at some point in the future. ------------- PR: https://git.openjdk.org/jfx/pull/445
