Subject: Schaeffer, Long-range planning in computer chess, 1983

ACM/CSC-ER,
Proceedings of the 1983 annual conference on Computers : Extending the human
resource

I just read this interesting paper (20+ years later!)...

Main idea:

Schaeffer essentially computes piece square table "bonuses" that depend on the
root position (e.g., plans like "king-side attack" or "try to occupy f5 with
your knight") and get added to the score of a branch in a path dependent way.

Some questions:

(1) Is this what Vincent Diepeveen sometimes referred to as "root processing"?

(2) Does anyone know how Schaeffer's Planner compared to Wilkin's PARADISE (in
terms of playing strength)?

(3) Is anyone experimenting with this or other types of path dependent eval?

Steven is of course working on long-range planning. And I think Uri has some
path dependent stuff. But have most people pretty much abandoned it?

Thanks,
Michael
