From now on all participating chess engines in CSVN tournaments will be tested, if the organisation think it is necessary, against already known engines with a similarity test.

For this the CSVN will use the similarity test created by Komodo's programmer Don Dailey. The similarity test makes a profile of the chess engine with help of software. These profiles can be compared to determine similarities with other chess engines.

When a percentage of 60% or more is found in the similarity test the tournament organisation will not accept the entry of the chess engine in the tournament. The organisation keeps the right to deviate from this rule.

For a more concise description of the similarity test we forward you to the study of Adam Hair (http://www.top-5000.nl/clone.htm). There you also find a link to the software, which can be freely downloaded.
