On the limits of computations with the floor function
1988
Information and Computation
Preserved Fulltext
Up to now, few models of computation with the power of evaluating discontinuous functions have been analyzed and few of their lower bounds or results on the decidability of languages are known. ...
These trees operate on real numbers and are able to compare real numbers, to evaluate functions on real numbers, and to evaluate certain discontinuous functions like the '?loor function." ...
We now define the computational model of "analytic computation trees" (ACTS). Informally, ACTS admit any function which composes the floor function and arbitrary analytic functions. ...
