1940 Chambers's Techn. Dict. 564/1 Multi-start worm, a worm in which two or more helical threads are used in order to obtain a larger pitch and hence a higher velocity ratio of the drive.

1958 Proc. Royal Soc. A. 248 99 It is probable that multi-start spiral gratings are of academic interest only, but single-start spirals offer the possibility of production by ruling on rotating blanks.

1971 B. Scharf Engin. & its Lang. xii. 158 With single-start worms, lead equals pitch, but on multi-start worms, it amounts to pitch × number of starts (i.e. number of thread sections in a plane at right angles to the axis).

1994 Jrnl. Amer. Statist. Assoc. 89 1553/1 This algorithm can be compared to the multistart algorithm used for solving global optimization problems.
