Figures of merit for digital multistep pseudorandom numbers

Abstract
The statistical independence properties of s successive digital multistep pseudorandom numbers are governed by the figure of merit ρ ( s ) ( f ) {\rho ^{(s)}}(f) which depends on s and the characteristic polynomial f of the recursion used in the generation procedure. We extend previous work for s = 2 and describe how to obtain large figures of merit for s > 2 s > 2 , thus arriving at digital multistep pseudorandom numbers with attractive statistical independence properties. Tables of figures of merit for s = 3 , 4 , 5 s = 3,4,5 and degrees ≤ 32 \leq 32 are included.
