Problem Definition
The three main types of mutations modifying biological sequences are insertions, deletions, and substitutions. The simplest model involving these three types of mutations is the so-called Thorne-Kishino-Felsenstein model [16]. In this model, the characters of a sequence evolve independently. Each character in the sequence can be substituted with another character according to a prescribed reversible time-continuous Markov model on the possible characters. Insertion-deletions are modeled as a birth-death process. Insertions can happen at the beginning of the sequence, at the end of the sequence, and between any two characters. It is possible to insert a character into the empty sequence. The time span between two insertions is exponentially distributed with parameter λ, and this parameter does not depend on the context of the position. The newborn character is drawn from the equilibrium...
