This approach, in the
event of a noise garble half way through the sequence, will
wander away from the correct answer.
Conversely, the Viterbi algorithm will look at the whole
sequence before deciding on the most likely final state, and
then `backtracking' through the
pointers to indicate how it
might have arisen. This is very useful in `reading through'
isolated noise garbles, which are very common in live data.
