Consider a large group of agents chasing a small group of moving targets. Assume each agent moves at constant speed toward the closest target. This paper studies the problem of controlling the agents indirectly by specifying the motion of the targets. In particular, it considers the problem of maintaining a minimum separation distance between each pair of agents, something that is impossible to...

This paper describes a new automatic method for Japanese predicate argument structure analysis. The method learns relevant features to assign case roles to the argument of the target predicate using the features of the words located closest to the target predicate under various constraints such as dependency types, words, semantic categories, parts of speech, functional words and predicate voic...

of n linearly independent vectors b1, . . . ,bn ∈ Rm in m-dimensional Euclidean space. For computational purposes, the lattice vectors b1, . . . ,bn are often assumed to have integer (or rational) entries, so that the lattice can be represented by an integer matrix B = [b1, . . . ,bn] ∈ Zm×n (called basis) having the generating vectors as columns. Using matrix notation, lattice points in L(B) c...
