Spent 2 days carefully crafting a highly optimised routine, then spent 3 minutes to write an unoptimised version for benchmarking. The latter ran 50% faster.

    premature optimization !

    I created an algorithm to compare to dijkstra, which id O(n^2)... Mine was O(n^n) and ran just as fast... Still don't know why

    @Folkmann, the big O notation measures complexity and not absolute performance. Give it an N that is large enough and the parity starts to show.

    @benhongh I know, but it's ment to estimate performance, so it still doesn't make sense that they are about equal in speed.
