Time-Space Tradeoffs for Set Operations

This paper considers time-space tradeoos for various set operations. Denoting the time requirement of an algorithm by T and its space requirement by S, it is shown that T S = (n 2) for set complementation and T S = ? n 3=2 for set intersection, in the R-way branching program model. In the more restricted model of comparison branching programs, the paper provides two additional types of results....

Time-Space Tradeoffs for Satisfiability

We give the first nontrivial model-independent time-space tradeoffs for satisfiability. Namely, we show that SAT cannot be solved simultaneously in n time and n1− space for any > 0 on general random-access nondeterministic Turing machines. In particular, SAT cannot be solved deterministically by a Turing machine using quasilinear time and √ n space. We also give lower bounds for log-space unifo...

Space-Time Tradeoffs for Emptiness Queries

We develop the rst nontrivial lower bounds on the complexity of online hyperplane and halfspace emptiness queries. Our lower bounds apply to a general class of geometric range query data structures called partition graphs. Informally, a partition graph is a directed acyclic graph that describes a recursive decomposition of space. We show that any partition graph that supports hyperplane emptine...

Time-Space Tradeoffs for the Memory Game

A single-player game of MEMORY is played with n distinct pairs of cards, with the cards in each pair bearing identical pictures. The cards are laid face-down. A move consists of revealing two cards, chosen adaptively. If these cards match, i.e., they bear the same picture, they are removed from play; otherwise, they are turned back to face down. The object of the game is to clear all cards whil...

Space-Time Tradeoffs for Distributed Verification

Verifying that a network configuration satisfies a given boolean predicate is a fundamental problem in distributed computing. Many variations of this problem have been studied, for example, in the context of proof labeling schemes (PLS), locally checkable proofs (LCP), and non-deterministic local decision (NLD). In all of these contexts, verification time is assumed to be constant. Korman, Kutt...
