[computer-go] Progressive unpruning in Mango 19x19

[Chaslot G (MICC)]

Dear all,

 

I did experiments on  19x19 Mango with 25000 simulations per move,
against GnuGo 3.6 level 0.

Without progressive unpruning, Mango wins 2.9% (250 games), and with
progressive unpruning, Mango wins 31% (400 games).

 

I proposed progressive unpruning in this paper:
http://www.cs.unimaas.nl/g.chaslot/papers/pmcts.pdf

Simultaneously, Remi Coulom proposed the same thing in this paper:
http://remi.coulom.free.fr/Amsterdam2007/ under the name "progressive
widening".

Question for native English speakers: do you think this technique is
best described by "progressive unpruning" or "progressive widening"?

 

Cheers,

 

Guillaume
