Le 04 avril 2017 à 14h00 en B107, Mireille Régnier nous parlera de : Accurate prediction of the statistics of repetitions in random sequences

Résumé : Repetitive patterns in genomic sequences have a great biological significance and also algorithmic implications. Analytic combinatorics allow to derive formula for the expected length of repetitions in a random sequence. Asymptotic results, that generalize previous works on a binary alphabet, are easily computable. Simulations on random sequences show their accuracy. As an application, the sample case of Archaea genomes illustrates how biological sequences may differ from random sequences.
