WebLecture05. Recall from last time that the Brute Force approach for finding a common 10-mer motif common to 10 sequences of length 80 bases was going to take up roughly 30,000 years. Today well consider alternative and non-obvious approaches for solving this problem. We will trade one old man (us) for another (an Oracle) WebGreedy Profile Motif Search Gibbs Sampler Random Projections 3 Section 1Randomized QuickSort 4 Randomized Algorithms Randomized Algorithm Makes random rather than deterministic decisions. The main advantage is that no input can reliably produce worst-case results because the algorithm runs differently each time.
