Subject: How many nodes?

Author: margolies,marc

When examining a position deeply with an engine, say for the purposes of placing
the evaluation of the position within a tree of candidate variations, how many
millions of nodes of testing are necessary in order to get the closest
approximation to that engines  best numerical assessment of a chess position and
its roughly corresponding possible variation move sequence?
Is there a numerical methods heuristic, or some other rule of thumb which I
might chose to use to attack the certainty issue? Maybe a statistical
regression? Should it be engine specific (and correlative to the kinds of
positions under assessment) or generic?
I welcome any suggestions here. Thanks-Marc
