Title

An Imperative Language Characterizing PTIME Algorithms

Abstract

Abstract State Machines of Y. Gurevich capture sequential algorithms, so we define the set of PTIME algorithms as the set of ASM programs computed in polynomial time (using timer-step principle). Then, we construct an imperative programming language PLoopC using bounded loop with break, and running with any data structure. Finally, we prove that PLoopC computes exactly PTIME algorithms in lock step (one step of the ASM is simulated by using a constant number of steps).

Keywords: ASM, computability, imperative language, implicit complexity, polynomial time, sequential algorithms, simulation.
