Most of the works on learning from networked data assume that the network is static. In this paper we consider a different scenario, where the network is dynamic, i.e. nodes/relationships can be added or removed and relationships can change in their type over time. We assume that the “core” of the network is more stable than the “marginal” part of the network, nevertheless it can change with ti...

Since the advent of evolution strategies many attempts have been done to improve the mutation operator [7]. The first enhancement could be seen in the introduction of a flexible step size. As a logical consequence later n step sizes, one per variable, were used. Highest flexibility is achieved with the correlated mutation but also quadratic growth of the number of strategy parameters [8]. A new...

The Besley-Coate model of representative democracy has the problem of multiple equilibria (Besley-Coate, 1997). We show that requiring the Besley-Coate political equilibria to be iteratively undominated at the voting stage re nes the set of (pure strategy) political equilibrium outcomes only for those cases where at least four candidates stand for election. This note complements the results of ...
