An Algorithmic Framework for Motif Discovery Problems in Weighted Sequences [chapter]

Hui Zhang, Qing Guo, Costas S. Iliopoulos
2010 Lecture Notes in Computer Science  
A weighted sequence is a string in which a set of characters may appear at each position with respective probabilities of occurrence.  ...  A common task is to locate a given motif in a weighted sequence in exact, approximate or bounded gap form, with presence probability not less than a given threshold.  ...  Due to uncertainties of weighted sequences, it turns out that handling weighted sequences is algorithmically challenging even for simple tasks such as exact pattern matching and even harder for more ambitious  ...
