This paper adds evidence structure to standard models of belief, in the form of families of sets of worlds. We show how these more fine-grained models support natural actions of “evidence management”, ranging from update with external new information to internal rearrangement. We show how this perspective leads to new richer languages for existing neighborhood semantics for modal logic. Our mai...

In this paper we propose a general variable neighborhood search approach for the balanced location problem. Next to large shaking neighborhoods, the embedded variable neighborhood descent utilizes three neighborhood structures that focus on different solution aspects. By a computational study, we show that this VNS outperforms existing methods with respect to average solution quality and stabil...

This note proposes various axiomatizations of contingency logic under neighborhood semantics. In particular, by defining a suitable canonical neighborhood function, we give sound and complete axiomatizations of monotone contingency logic and regular contingency logic, thereby answering two open questions raised by Bakhtiari, van Ditmarsch, and Hansen. The canonical function is inspired by a fun...

es on how structural characteristics affect various outcomes. One form of this research tests whether structural characteristics of neighborhoods affect various aggregate outcomes, such as crime, economic vibrancy, cohesion, or even death from heat waves (Browning et al. 2006). Another form of this research employs multilevel models to test whether the structural or cultural characteristics of ...

There is a substantial research literature on residential mobility in general, and the role of housing space in triggering moves in particular. The authors extend that research to mobility in British housing markets, using data from the British Household Panel Survey. They confirm the applicability of the general residential mobility model and also confirm the value both of pooled cross-section...

The Variable Neighbourhood Search (VNS) is a recent metaheuristic for solving optimization problems whose basic idea is systematic change of neighborhood within a local search. In this paper we present basic rules of the VNS and its extensions. We briefly summarize the most relevant applications in Artificial Intelligence. These applications comprise classic tasks, like constraints satisfaction...

Using microdata from CoreLogic and Gallup between 2008 and 2014, we study the impact of foreclosures on individual well-being. We identify the causal effect of foreclosures by instrumenting them using variation in interest rate spikes associated with different types of adjustable rate mortgages (ARMs), conditional on controls and zipcode and time fixed effects. We find that a 10% rise in forecl...

In this paper, the dynamic allocation of camera resources for moving objects is presented as a model of partial constraint satisfaction problem. The purpose of the camera allocation is described as some simple constraint. The solution is reflexively searched in order to decide the allocation of each camera. The search neighborhood of the solution is limited to the partial solution for each came...
