Up Topic Rybka Support & Discussion / Aquarium / Project score bounds: relative to root score?
- - By retep1 (***) [de] Date 2011-04-24 12:09
I read in the manual under
"9.4.
Next, switch to the IDeA tab.
"Project score bounds limits the analysis to variations which have a centipawn evaluation within the specified bounds."
New in Aquarium 2011 is the check-box: "relative to root score"?
I dont understand the function - please explain by a given example.

Relative to root score works as follows.

Let's say that the current root score is 0.00 and your Project score bounds (PSB) are -50 to +50. This means that IDeA will analyze (extend and create alternatives) for positions in the tree with a score between -50 and +50.

An hour later the root score increases to +0.15. Since the PSB are relative to the root score they are now effectively -35 to +65 (-50+15 to 50+15), so IDeA will analyze positions with a score in that interval.

> when does it make sense?


it makes sense when you want to accomplish something like Dadi says (it could be every time).
Its just a filtering tool. Basically all the time. You dont have to know the root score too use project bound know..

For example -100 to +100 (relative checked on) means you want to expand every move that is at most one pawn eval more or less than root (which is "best" move of subtree)
