Finding the biologically optimal alignment of multiple sequences

摘要

Objective:Deterministic annealing, which is derived from statistical physics, is a method for obtaining the global optimum in parameter space. During the annealing process, starting from high temperatures which are then lowered, deterministic annealing deterministically find the (global) optimum at each temperature. Thus, deterministic annealing is expected to be more computationally efficient than stochastic sampling strategies to obtain the global optimum. We propose to apply the deterministic annealing technique to the problem of efficiently finding the biologically optimal alignment of multiple sequences.
