Bill Gosper

Bill Gosper (born in 1943) (complete name Ralph William Gosper, Jr.) is a mathematician and data processing specialist étasunien born with Pennsauken, New Jersey. Gosper is known for several work relating to the representation of realities by continued fractions and for a algorithm (Algorithm of Gosper) of determination of closed Forme of certain identities hypergeometric S.

He is regarded with Richard Greenblatt as one of the founders of the community of the Hacker S and profits from a recognition in the community of the programmers in Lisp.

Gosper returns to the Massachusetts Institute off Technology in 1961 and obtains its bachelor' S dismantles in mathematics in 1965. After having followed the course of programming in second year of John McCarthy, Gosper returns to the laboratory of artificial intelligence of MIT.

Its contributions to formal calculation include/understand the memo HAKMEM and the system Maclisp of MIT. Gosper is also recipient in the development of the system of formal calculation Macsyma, working then with Symbolics and Macsyma, Inc. with the commercial releases improved of the system.

Gosper is then strongly interested in the Jeu of the life proposed by John Horton Conway. Conway conjectured the existence of reasons growing indefinitely and offered a reward to which will exhibera an example of such reasons. Gosper was the first to find an example: the Canon with sailplane and consequently empoché the reward. In the same field, Gosper is at the origin of the algorithm Hashlife which makes it possible to improve the computing speed of the reasons of the play of the life.

Of 1974 with 1977, Gosper works with the Université Stanford in California. He collaborates with Don Knuth in the writing of the second volume of The Art off Computer Programming .

Since, Gosper worked or was used as consultant for Xerox PARK, Symbolics, Wolfram Research, the Lawrence Livermore Laboratory and Macsyma Inc..
