Joël Rivat [1]
Joël Rivat,
a French mathematician and computer scientist at University of the Mediterranean, Marseille. Joël's research covers analytic number theory, beside other things, the Piatetski-Shapiro Prime Number Theorem [2].
Bitboards
As computer chess programmer, Joël Rivat is early bitboard proponent, and author of the chess engine Chess Guru. He started chess programming in conjunction with C. Marche, G. Le Blanc in 1990, and rewrote everything using bitboards. After Robert Hyatt started using bitboards too, discussions and sharing new ideas permitted to improve the technique considerably [3] .
