Yes, the code involving the DP algorithm I put in had a bug in it - not from the DP algorithm itself but the assumptions that fed into it - which went undetected for some time because of how complex the DP algorithm was and how hard it was to evaluate. It only caused a minor performance quirk (not a actual semantic error) so was hard to find. A cautionary tale about being overly clever-clever I suppose.
