Erratum to: Drift analysis and average time complexity of evolutionary algorithms: [Artificial Intelligence 127 (2001) 57–85]

The proof of Theorem 6 in the paper by J. He and X. Yao [Artificial Intelligence 127 (1) (2001) 57–85] contains a mistake, although the theorem is correct [S. Droste et al., Theoret. Comput. Sci. 276 (2002) 51–81]. This note gives a revised proof and theorem. It turns out that the revised theorem is more general than the original one given an evolutionary algorithm with mutation probability p_m=1/(2n), using the same proof method as given by J. He and X. Yao [Artificial Intelligence 127 (1) (2001) 57–85].     

The Institut Blaise-Pascal (1946-1969) from Couffignal's Machine to Artificial Intelligence

The Institut Blaise-Pascal, created in 1946, was France's first laboratory devoted to electronic computers, analog as well as digital. Its analog division, under L. Malavard, developed rheological methods that had been initiated in the early 1930s. Ifs numerical division was headed first by L. Couffignal who did not succeed in building his electronic calculator, based on a very particular design; then by R. de Possel, who actively developed computer facilities, computer science teaching and research, and undertook to achieve a universal optical character recognition system. The Institut Blaise-Pascal was divided into several independent teams in 1969.     

Erratum to “FaCE: a tool for three body Faddeev calculations with core excitation” [Comput. Phys. Commun. 161 (2004) 87-107]

The subroutine FANCDEF3 in the code FaCE published as ADTW in CPC 161 (2004) 87, is corrected.
