If you want to add more tests: https://oeis.org/A006884 and https://oeis.org/A006885 contain the relevant sequences.
function pmax = peakOfPeaks(nmax)
How would I speed this up?
If I input nmax = 2^60, my program cannot finish.
This solution will fail for nmax = 2; so I had to swap the order of two lines. See Solution 1088355.
i'm totally lost with this!
wrong, corrected in soln 329062
I only feel justified in doing this because the previous best answer was a look-up table. :P
Clever pattern, but still gaming the system. This is not the absolute highest Collatz peak as you go to infinity. Yuval, you should be ashamed of submitting this without apologies.
This really doesn't solve the problem it's just gaming the results.
