I've been playing with an alpha beta searcher to see if it's feasible
using play-outs as an evaluation function in a program that does an
alpha beta global search.
I'm using the heavy play-out version of Lazarus and doing tests of up
to 3 ply searches on 9x9. The old 1500 ELO rated AnchorMan is a

Probably not, because the Hessian has significant non-diagonal values.
But I expect it would still converge in less iterations than MM.

Hi,
Minorization-maximization is a simple optimization method, and I agree
that it is likely that more efficient algorithms can be applied.
Newton's method implies estimating the inverse of the Hessian matrix.
Really computing the inverse has a cost cubic in the size of the matrix,
so it is
