We consider a more general setting, called the pairwise Markov model (PMM), where the joint process consisting of finite-state hidden process and observation process is assumed to be a Markov chain.

We consider a bivariate Markov chain $Z=\{Z_k\}_{k \geq 1}=\{(X_k, Y_k)\}_{k \geq 1}$ taking values on product space ${\cal Z}={\cal X} \times{ \cal Y}$, where ${\cal X}$ is possibly uncountable space and ${\cal Y}=\{1,\ldots, |{\cal Y}|\}$ is a finite state-space.

We consider the problem of estimating the maximum posterior probability (MAP) state sequence for a finite state and finite emission alphabet hidden Markov model (HMM) in the Bayesian setup, where both emission and transition matrices have Dirichlet priors.

In those models, a new genome is born according to the breeding process, and then a genome is removed according to the selection scheme that involves fitness.

The same iterative algorithm for improving the Viterbi alignment can be used in the case of peeping, that is when it is possible to reveal hidden states.

Furthermore, simple modifications of the classical criteria for hidden path recognition are shown to lead to a new class of decoders.
