I do [Save hash]  and later in a quite different position [Load hash].

(1) Probably  it is not useful?
(2) But however does Rybka recognize hash collisions here?
(3) And in Persistent hash, after merging some alien files, the same problem could be more complex.

Thx, Emil

Probably you want to know if after the hash load, Rybka will recognize the positions she analyzed before and remember her old analysis? The answer is yes - this is the point.

No problem, everything is prioritized by depth and age.

Vas

ps. "hash collision" is a technical term for different positions mapping to the same hash entry. This almost never happens and in practice can be ignored.
