Urban Koistinen,
a Swedish mathematician and computer scientist. While affiliated with the Royal Institute of Technology in Stockholm, he was active in computer chess programming [2], and introduced none rotated bitboard techniques to determine sliding piece attacks in 1997 [3]. Urban Koistinen became editor of the Swedish PLY Computer Chess Magazine of the SSDF in 1997 [4], and in 2001, he proposed an efficient indexing scheme for endgame bitbases with few men, which was published under the GNU Free Documentation License [5].
