9 Step 8. Determination of t and 8. To be able to determine ink, from (9.38)
we need
A A
min(Uk_l) -- max(Lk) >__ 0 9.44
This gives a relation between t and 8 that is used to choose suitable values.
9 Step 9. Determination of the selection constants mk using expression (9.38).
Moreover, determine the range ofF'[ j] as
[rco + min(H1) -
Cmax] t
~
~[j] ___ [r~ + max(H1) +
]eminl] t

Part 2b: Other Selection Methods
In algorithms using a higher radix (r > 4), implementing a selection function
based on selection constants becomes quickly impractical. ...
