PostPost subject: Singular Margin based on depth?    Posted: Sat Feb 11, 2012 4:37 pm Reply to topic Reply with quote

One of the ideas in the Ippolit based programs (and in Critter) is that when doing the test for Singularity (for Singular Extension), the margin is proportional to depth. Aside from whether this tests well or not, can anyone explain the rationale for this idea? It is not at all obvious to us why a deeper search should require a larger margin. One might even argue that move ordering gets better with depth, so a smaller margin might be needed at higher depths.
