Computer Go Ladder

The Computer Go Ladder was an early competition between Go playing programs on 9x9 and 19x19 board sizes, run by Eric Pettersen since 1995.

In August 2008 it was noted as having "not had much activity lately, largely being supplanted by the Computer Go Server."

The last recorded result on the website is from April 30th, 2009.
