As the amount of molecular data (e.g. DNA sequence s) quickly grows\, efficient algorithms become increasingly important to analyze this data. A maximum-likelihood approach with models for nucleo tide evolution allows us to use all the sequence data\, but is a computa tionally expensive approach. The number of possible trees also grows rap idly as we include more species. It is therefore necessary to use heuris tic search methods to find good hypotheses for the “true” tree. Evolutio nary algorithms (EA) is a class of such search/optimization algorithms t hat has been shown to perform well in other areas where the search space is large and irregular. I will explain my approach and my findings from using an evolutionary algorithm for inferring phylogenies from molecula r data.\n\nTags: galois\, tech talk\, algorithms\, classification\n\nImp orted from: http://calagator.org/events/1250463783 URL:https://corp.galois.com/blog/2013/3/7/tech-talk-inferring-phylogenies -using-evolutionary-algorithm.html SUMMARY:Galois Tech Talk: Inferring Phylogenies Using Evolutionary Algori thms LOCATION:Galois\, Inc: 421 SW 6th Ave. Suite 300\, Portland OR 97204 US SEQUENCE:1 END:VEVENT END:VCALENDAR
