Abstract
We study the ergodic optimization problem for a class of typical maps including Axiom A attractors, Anosov diffeomorphisms, subshifts of finite type and uniformly expanding systems. In connection with the conjecture proposed by Yuan and Hunt in 1999, we prove that when the space of observables is with or (if well defined), the optimal (minimizing or maximizing) orbits are generically periodic, thus confirming the conjecture in those cases.
