Gunnar Andersson,
a Swedish computer scientist and mathematician, Ph.D. from Royal Institute of Technology in 2000 under Viggo Kann on the topic of approximation algorithms for optimization versions of NP-complete decision problems [1] . As Othello programmer, Gunnar Andersson is primary author of the strong Othello program Zebra [2] and its Windows freeware incarnation WZebra [3], already incorporating advanced bitboard techniques like Kogge-Stone Algorithm. An older 2003 MMX implementation of Dumb7Fill in inline assembly was used to determine mobility [4], while the implementation by co-author Toshihiko Okuhara in Zebra looks parallel prefixed [5].
