We consrder asynchronous general topology dynamic networks of identical nameless nodes wzth worst-case transient faults. Starting from any faulty configuration, our protocols self...
We consider the problem of approximating a convex gure in the plane by a pair (r; R) of homothetic (that is, similar and parallel) rectangles with r C R. We show the existenc...
One-way cellular automata with restricted nondeterminism are investigated. The number of allowed nondeterministic state transitions is limited to a constant. It is shown that a lim...
In the past decade, the programming languages C++, FORTRAN 90 and Oberon-2 allevolved from their ancestors. This invites to reflect upon the suitability ofthese modern programming...
Abstract. A solid object in 3-dimensional space may be described by a collection of all its topologically distinct 2-dimensional appearances, its aspect graph. In this paper, we st...
