The multi-vehicle covering tour problem is de"ned on a graph G"(<6=, E), where = is a set of vertices that must collectively be covered by up to m vehicles. The problem consists of determining a set of total minimum length vehicle routes on a subset of <, subject to side constraints, such that every vertex of = is within a prespeci"ed distance from a route.(More)
The central drift chamber for the BaBar detector at the PEP-II B-factory at SLAC is a cylindrical chamber with a length of 280 cm and outer radius of 81 cm. It consists of 40 layers of small hexagonal cells arranged in 10 axial and stereo super layers. In order to minimize multiple scattering, light materials are used for the mechanical structure, and the(More)
