'''Freedom''',<br/>
a chess program by [[Nils Barricelli]]. It participated at the [[WCCC 1974|First World Computer Chess Championship]] 1974 in [https://en.wikipedia.org/wiki/Stockholm Stockholm], running on a [[CDC Cyber|CDC Cyber 74]]. It lost versus the strong [[CHAOS]] and [[Ribbit]] in round 1 and 2 respectively, and had a lucky draw from [[Tell]].

Barricelli, at that time affiliated with the [https://en.wikipedia.org/wiki/University_of_Oslo Oslo University] <ref>[https://www.game-ai-forum.org/icga-tournaments/program.php?id=50 Freedom's ICGA Tournaments]</ref>, had already experience in chess programming for his [[Nils Barricelli#Symbioorganisms|Symbioorganisms]] experiments at [[University of Manchester]] in 1962, where [[Alex Bell]] worked for him and wrote his first [[Move Generation#Legal|legal-move generator]]. Freedom's [[Evaluation|evaluation]] was primary based on the ratio of own and opponents [[Mobility|mobility]] aka number of [[Legal Move|legal moves]].

=Quotes=
[[Tony Marsland]] mentioned Freedom, [[Papa]] and other programs participating the [[WCCC 1974]] in his handwritten notes <ref>[http://webdocs.cs.ualberta.ca/~tony/Public/Awit-Wita-ComputerChess/Wita-base/WitaNotes/wita-awit%2319-box2.pdf wita-awit#19-box2.pdf] from [http://webdocs.cs.ualberta.ca/~tony/Public/Awit-Wita-ComputerChess/Wita-base/WitaNotes/ Wita Notes] by [[Tony Marsland]]</ref> on the [[Jean Hayes Michie|Hayes]] and [[David Levy|Levy]] book <ref>[[Jean Hayes Michie|Jean E. Hayes]], [[David Levy]] ('''1976'''). ''[http://www.getcited.org/pub/101724802 The world computer chess championship, Stockholm 1974]''. University Press (Edinburgh) ISBN 0852242859</ref> :
[[Freedom]] and [[Papa]] both use [[Mobility|mobility]] as their primary term in their [[Evaluation function|evaluation functions]]. As with [[Awit|Wita]], both use the ratio of computer's moves / opponent moves. Papa and Wita also multiply by the ratio of the squares controlled and Papa goes one step further and takes the logarithm of this product to form the "[[Papa#Entropy|entropy]]" of the position. The true merit of this entropy over the product ratio was not made clear, but it does ensure that in extreme situations the evaluation remains more closely bounded.
