Collapsing Degrees via Strong Computation

Though Berman and others have provided powerful techniques to collapse nondeterministic degrees at and above nondeterministic linear space, and Immerman and Szelepcsenyi have provided techniques that collapse even sublinear nondeterministic space classes, it has remained an open problem whether any collapses could be proven for sublinear nondeterministic space degrees. This paper provides the f...

Collapsing Polynomial-Time Degrees

For reducibilities r and r′ such that r is weaker than r′, we say that the r-degree of A, i.e., the class of sets which are r-equivalent to A, collapses to the r′-degree of A if both degrees coincide. We investigate for the polynomial-time bounded many-one, bounded truth-table, truth-table, and Turing reducibilities whether and under which conditions such collapses can occur. While we show that...

Fault Collapsing via Functional Dominance

A fault fj is said to dominate another fault fi if all tests for fi detect fj . When two faults dominate each other, they are called equivalent. Dominance and equivalence relations among faults around a Boolean gate are called \structural" and are used for fault collapsing in large circuits. Some fault equivalences, that cannot be determined by the structural analysis, can be found by \function...

Heterogeneous Strong Computation Migration

The continuous increase in performance requirements, for both scientific computation and industry, motivates the need of a powerful computing infrastructure. The Grid appeared as a solution for inexpensive execution of heavy applications in a parallel and distributed manner. It allows combining resources independently of their physical location and architecture to form a global resource pool av...
