The method of successive grids for reduction of function storage requirements*

R. L. Boyell

Pennsylvania Research Associates Inc., Philadelphia, Pa, USA

A method is analysed for reducing storage requirements of arbitrary but relatively well-behaved functions of any number of variables. The method consists of storing successive digits of the words representing the values of the function according to grids of successively finer meshes. The advantage is illustrated as dependent upon the size of the function table to be stored, being well suited to computers operating with variable word length.
