Unformatted text preview: normal forward/backwards pass. Hence, each such forward/backwards pass can have the same process repeated. Hence, further divide each of the length-T /b subsegments into subsubsegments of length T /b2 . Each of the subsubsegments look again like a standard forward-backwards procedure and so can be still further subdivided into length-T /b3 sequence. The recursion proceeds to a depth of k , leading to segment lengths T /bk (base case) where we perform normal forward-backward.
