Re: Mind your language

I know it may not be a popular opinion but I think they should have had
Pascal 1
Pascal 2
Pascal 3
Pascal 4
etc etc.

But each to their own.............

This is strange ?

I have found that in one game, my program locked up when it reaches depth = 11 in the iterative search. If I change the first block of code to the second block it then works ??? But the code gives the same logic/conditions ??? (I'm using Free Pascal). Have I missed something ? (the indenting has bee...

Yes, you guessed it, I found a bug.
Or should I say a dumb logic mistake.

Re: How do you fix this.

Yep, it does return zero.....and I couldn't agree more with your reasoning ??
When I set up the position again and try to reproduce it.....guess what !! I can't yet. So there must be
a bug somewhere. Ahh well, gives me something to think about while the golf course is closed.

Re: How do you fix this.

I do, and the program avoids it for a while but eventually fails.....
Maybe I should check the 3 fold code.
Hmm ?

How do you fix this.

It's the end game. White is 3 pawns ahead, but black keeps threatening to take 1 of 2 pawns.. white shuffles it's king back and forth to save both pawns resulting in 3 fold rep. If white gave up one pawn he could win the game, but it's beyond the horizon.
Any way to remedy this ???

Root Moves

Hey all.

My program does not have a seperate root search and I have noticed that the root node is an 'All node'.
Is this always going to be the case ?
Can I change/improve this ?
