If there are no constraints on the rate matrices and Hamiltonians available to a driving protocol, one can transform a system from any initial Hamiltonian and state distribution to any final Hamiltonian and state distribution with zero EP. We investigate the minimal EP that must be incurred to implement such a transformation, if there are constraints on the set of allowed Hamiltonians and rate matrices. Our first result is that zero EP can be achieved even when the Hamiltonian has only a single controllable degree of freedom, as long as there are no constraints on the rate matrix (beyond detailed balance). We then derive non-trivial bounds on the EP that arise in the presence of simultaneous constraints on the Hamiltonian and the rate matrix. These bounds are determined by an effective non-equilibrium free energy, which reflects the work value of a distribution and Hamiltonian under a set of constraints. These results have implications for the thermodynamics of information, in that allow one to decompose acquired information into &#8220;useful&#8221; bits and &#8220;useless&#8221; bits.<\/p><p><strong>BIOGRAPHY: <\/strong>Dr. Artemy Kolchinsky is a postdoctoral fellow at the Santa Fe Institute (New Mexico, USA).<\/p><p>His work lies at the intersection of information theory, statistical physics, and machine learning.
