Shmuel Gal

From Wikipedia, the free encyclopedia

Shmuel Gal (Hebrew: שמואל גל‎) is a mathematician and professor of statistics at the University of Haifa in Israel.

He devised the Gal's accurate tables method for the computer evaluation of elementary functions.[1][2] With Zvi Yehudai he developed in 1993 a new algorithm for sorting which is used by IBM.[3]

Gal has solved the Princess and monster game [4] and made several significant contributions to the area of search games.[5][6][7]

He has been working on rendezvous problems with his collaborative colleagues Steve Alpern, Vic Baston, and John Howard.[8][9][10][11]

Gal received a Ph.D. in mathematics from the Hebrew University of Jerusalem (thesis advisor: Aryeh Dvoretzky).
