Go up one level in this thread


>>Rebel analyze a game and its moves in the following way:
>>Stage one: Analyze what Rebel would have played (on the given time-level)
>>Stage two: Analyze the actual move played (till the ply-depth of stage-one)

>>Suggestion: after stage-one if "Rebel_move = move played in game"
>>skip stage-two and copy analysis results from stage-one into stage-two.

>>Is that what you want?

>Yes.

>>In this respect remember that stage-two is much faster than stage-one.
>>In stage-one all moves have to be searched. In stage-two only the "move
>>played in the game" has to be searched till the given depth from stage-one.
>>Stage-two is simply done by an internal "analysis include". As you know
>>such a search is usually 3-5 times faster. So the real time gain is not much.
>>But I assume that is not a good answer :)

>I haven't seen a much different eval yet and I can't remember getting Rebel at

That's the point, an analysis with unequal ply-depth's is pretty worthless so
that's why stage-two searches as deep as stage-one for a good comparison.


>That is indeed confusing. It should be possible to let Rebel analyze all the

Easy, select all games from the database (button select all) or select just
a few with the mouse then go to the "utilities" menu and select "analyze
game". That's it as Rebel will analyze all games you selected.
