Title: Randomized Algorithms for Motif Detection Speaker: Wang Lusheng CityU Date: Friday, March 11, 2005 Time 11-12 Venue: Room 4480, HKUST Near lifts 25-26 Abstract Motif detection is an important problem that has many applications such as finding targets for potential drugs, design of diagnostic probes, PCR primers design etc. The problem can be described as follows: Given two groups of sequences B and G, find a length-L string that appears in every sequence in B and does not appear in anywhere of the sequences in G. When errors are allowed, the problem is NP-hard. In this talk, we will discuss theoretical algorithms as well as practical software on this topic.
