Space---Time Trade-offs for Stack-Based Algorithms

Luis Barba; Matias Korman; Stefan Langerman; Kunihiko Sadakane; Rodrigo I. Silveira

In memory-constrained algorithms, access to the input is restricted to be read-only, and the number of extra variables that the algorithm can use is bounded. In this paper we introduce the compressed stack technique, a method that allows to transform algorithms whose main memory consumption takes the form of a stack into memory-constrained algorithms. Given an algorithm
