Re: How long to see mate - for stronger programs

Post by Eelco de Groot »

Rebel 14.1 MOD could find the Mate in 14 in just over one hour, on single core. It can only use the one core of course. But it sees the right move from zero seconds :)

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
