Approximate Shortest Path Queries Using Voronoi Duals
We propose an approximation method to answer point-to-point shortest path queries in undirected edge-weighted graphs, based on random sampling and Voronoi duals. We compute a simp...

Automatic Structures of Bounded Degree Revisited
Abstract. It it shown that the first-order theory of an automatic structure, whose Gaifman graph has bounded degree, is decidable in doubly exponential space (for injective automa...

Ludics Nets, a game Model of Concurrent Interaction
We propose L-nets as a game model of concurrent interaction. L-nets, which correspond to strategies (in Games Semantics) or designs (in Ludics), are graphs rather than trees; the ...

A Logic-Based Formulation of Active Visual Perception
Building on earlier attempts to characterise robot perception as a form of abduction, this paper presents a logical account of active visual perception in the context of an upper-...
