| I'm fairly sure my solution is provably optimal through a parity argument (the number of steps required to get to exit if the gate cell is initially left untouched must be even, and the distance from the goal the generation before it is on must be greater than 1. so for even parity this is the fastedt possible. for odd parity, you need to go up and around the bot, which takes 4 moves, which is at least 3 moves slower as the parity change saves one move (and yes, I have found the 53 move solution.) | ||||
