We present the problem of Ergodic Optimization for the shift on
the sequences of naturals (positive integers) with a irreducible transition
matrix, that is, such that the dynamics is transitive. With some uniformity
on the potential, we're able to give a simple and dynamical proof of the
existence of a maximizing measure on this context.
