Widespread availability of location aware devices (such as GPS receivers) promotes capture of detailed movement trajectories of people, animals, vehicles and other moving objects. We investigate spatio-temporal movement patterns in large tracking data sets, i.e. in large sets of polygonal paths. Specifically, we study so-called ‘popular places’, that is, regions that are visited by many entitie...

We study the problem of matching applicants to jobs under one-sided preferences; that is, each applicant ranks a non-empty subset of jobs under an order of preference, possibly involving ties. A matching M is said to be more popular than T if the applicants that prefer M to T outnumber those that prefer T to M . A matching is said to be popular if there is no matching more popular than it. Equi...

In the paper we study popular b-matchings, which in other words are popular many-to-many matchings. The problem can be best described in graph terms: We are given a bipartite graph G = (A ∪H,E), a capacity function on vertices b : A ∪H → N and a rank function on edges r : E → N . A stands for the set of agents and H for the set of houses. Each member of a set of agents a ∈ A has a preference li...
