'''Andreas Lothe Opdahl''',<br/>
a Norwegian computer scientist and professor at ''Department of Information Science and Media Studies'', [https://en.wikipedia.org/wiki/University_of_Bergen University of Bergen].
His research focuses on development, management and use of enterprise models which support [https://en.wikipedia.org/wiki/Information_systems information systems] development and operations,
in particular enterprise models for interoperability between enterprises and their information systems, and before, on [https://en.wikipedia.org/wiki/Software_performance_testing software performance evaluation].
In 1993, along with [[Bjørnar Tessem]], he contributed to computer chess at the [[Advances in Computer Chess 7]] conference on the topic of [[Planning|Long-Term Planning]].

''Abstract'' <ref>[[Andreas L. Opdahl]], [[Bjørnar Tessem]] ('''1994'''). ''Long-Term Planning in Computer Chess''. [[Advances in Computer Chess 7]]</ref>
A Framework for long-term planning in computer chess is sketched and as an example the [https://en.wikipedia.org/wiki/King%27s_Indian_Defence King's Indian Defence] is proposed schematically. Chess plans are represented as logical initiation, fulfilment and abandonment conditions and as modifications to the parameters used to [[Evaluation|evaluate]] [[Node|nodes]] in a [[Minimax|minimax search]]. Several such plans are than combined to form a [https://en.wikipedia.org/wiki/Directed_acyclic_graph directed acyclic graph] (DAG) through which the program moves as the game progresses. Rules are represented to support creation, maintenence and consistency of the resulting plan DAGs. Funally, further work is suggested.
