I tried Deepnest. it was fun seeing it in action and doing the dirty work for me, but then i found out that i can do better myself :). really, i gave it enough time to solve a given puzzle ( i cut shapes to fit in my small laser bed) but even though it came up with some nice solutions i managed to pack the shapes even better. can’t say, retrospectively, that i would have managed better without seeing the solutions Deepnest came up with, but the solution i reached is not like tightening the gaps, but a different solution altogether. can’t say i will do better with many small crazy stuff, but for bigger parts we humans can still contribute and win.
