Leslie G. Valiant, whose work on holographic algorithms was the subject of a recent column in American Scientist and a brief note here on bit-player, has won the 2008 EATCS Award of the European Association for Theoretical Computer Science. In addition to the work on holographic algorithms, the EATCS cites Valiant’s contributions of computational learning theory, neuroscience, and several areas of complexity theory, including the study of enumeration problems.
