BDDs and Compression Results
This thesis investigates the use of Binary Decision Diagrams (BDDs) to see if they are a more compact and more efficiently-accessed way of storing chess endgame tables (EGTs).
The compression results seem, on aggregate, to be no better than achieved already with Nalimov EGTs.
The access-times do not really compare 'like with like' as the BDD access-times require the BDD to be (unscalably) in RAM, which a Nalimov EGT would not be.
BDDs are also at the centre of Joe Hurd's paper, producing the EGT results by theorem-proving techniques using HOL, q.v.
