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”?
