Physical computational devices have operational constraints that necessitate nonzero entropy production (EP). In particular, almost all real-world computers are “periodic” in that they iteratively apply the same physical process, and are “local” in that not all physical variables that are statistically coupled are also physically coupled. Here we investigate the nonzero EP that necessarily results from these constraints in deterministic finite automata (DFA), a foundational system of computer…

A variant of this modularity mismatch cost for DFA was derived in Ref. [34], for DFA operating in steady state

    EP is positive if the sequences (Λi−2,Λi−1, Λi) = (a or b, b, a) and (Λi−2,Λi−1, Λi) = (b, a, a) both have non-zero probability

      This observation was made for σ mod alone in Ref
