- So is my question,
-
- i) Consider an alphabet of P different symbols.
- ii) Consider a sequence of L symbols from this alphabet.
- iii) Count the number of differents K-tuple in the sequence.
- (a K-tuple is a subsequence of length K and overlapping
- of K-tuples is allowed).
-
- Now you get a "macro-description" of the sequence in terms of
- K-tuple frequency. For instance, with an alphabet of two
- symbols '0' and '1' and the sequence of 5 symbols '00100', the
- "macro-description" for K=2 is
- 00 -> 2 times
- 01 -> 1 time
- 10 -> 1 time
- 11 -> 0 time
-
- For a given "macrodescription", how many different sequences
- can be found ?
