Hello!

Is the formula for ideal branching factor by brute force search simple or
complicated? Could it be computed as: "Square of average number of moves in each
ply".

If, for instance, we have average number of nodes in each ply 25, then branching
factor is:

25^=5  (effective branching factor is 20%)

If number of average moves is 30 then:

30^=5.477 (effective branching factor is 18.25%)

and so like.

Also, I speak about search where all complications of move ordering is present
as well as alpha-beta. But extensions, hash table, null move and so like are not
in the program.

Thanks for response!
Leonid.
