R. H¨aggkvist proved that every 3-regular bipartite graph of order 2n with no component isomorphic to the Heawood graph decomposes the complete bipartite graph K6n,6n. In [2] the ...
In this paper, we present an account of classical Logic Programming fixed-point semantics in terms of two standard categorical constructions in which the least Herbrand model is ...
Although the energy required to perform a logic operation has continuously dropped at least by ten orders of magnitude since early vacuumtube electronics [1], the increasing clock ...
We study the problem of drawing a graph-theoretic path where each edge is assigned an axis-parallel direction in 3D. Di Battista et al.[3] gives a combinatorial characterization f...
We characterize the traceability properties of linear codes. It is well known that any code of length n and minimum distance d is a c-TA code if c2 < n/(n−d). In this paper, w...
