Is it only me or the scoreboard isn't showing the names correctly?

    Their CSS is broken because the table is too wide. Remove "._42ef { overflow: hidden; }" in dev console (or alternatively add "._47zq ._47zr {width: 10px;}"), then you'll get smth readable, though not nice.

rng_58 won the tournament first time.Congrats to him. He will be back for topcoder open so it will be interesting this year.

Looks like this year problem was tough or error prone.

Did anything odd happen to bmerry? It's quite surprising to see him fail all 6 submissions.

    If I recall correctly, Snake and Ladder was a tiny error, Rainbow String was an overflow where he wasn't using longs, and his solution to Grundy Graph wasn't real, it was just an end-of-contest submission (didn't work on samples).

    Yeah, that's probably my worst performance ever:

    • Snake and Ladder: I didn't handle the N=1 case (or more generally, 2 empty cells on the same rung)
    • Boomerang Crews: My algorithm was bogus, but passed all the samples.
    • Grundy Graph: not a real submission
    • RNG: an error in the formulae for expected time to respawn when trying to move a set distance
    • Maximinimax: initial range for binary search was too small (the given graph can't have minimax flow more than 2000000, but the augmented graph can)
    • Rainbow String: integer overflow
