A reversible and conservative model based on rational signal machines for Black hole computation
Résumé
In the context of Abstract geometrical computation, it has been proved that black hole model (and SAD computers) can be implemented. To be more physic-like, it would be interesting that the construction is reversible and preserves some energy. There is already a (energy) conservative and reversible two-counter automaton simulation. In the present paper, based on reversible and conservative stacks, reversible Turing machines are simulated. Then a shrinking construction that preserves these properties is presented. All together, a black hole model implementation that is reversible and conservative (both the shrinking structure and the universal Turing machine) is provided.
