Abstract
A description of a new method for aligning biological sequences is presented. It is based on a formulation as a Markov decision optimization problem. Alignment is obtained by solving an associated linear programming problem. In this paper we show that the sensitivity of the alignment to changes in the cost matrices can be quanitified. This is in contrast to conventional dynamic programming based methods.
