Deterministic Computations in Time-Varying Graphs: Broadcasting under Unstructured Mobility
Most highly dynamic infrastructure-less networks have in common that the assumption of connectivity does not necessarily hold at a given instant. Still, communication routes can be...

Computing minimum distance between two implicit algebraic surfaces
The minimum distance computation problem between two surfaces is very important in many applications such as robotics, CAD/CAM and computer graphics. Given two implicit algebraic ...

A Linguistic Characterization of Bounded Oracle Computation and Probabilistic Polynomial Time
We present a higher-order functional notation for polynomial-time computation with arbitrary 0; 1-valued oracle. This provides a linguistic characterization for classes such as np...
