Symmetry Breaking Using Value Precedence
, 2009 We present a comprehensive study of the use of value precedence constraints to break value symmetry. We first give a simple encoding of value precedence into ternary constraints that is both efficient and effective at breaking symmetry.

Strategic Flip‐Flopping in Political Competition
International Economic Review, EarlyView.ABSTRACT We study candidates' position adjustments in response to information about voters' preferences. Repositioning allows candidates to move closer to the median voter, but it incurs financial and electoral costs. In a subgame‐perfect equilibrium, candidates diverge from the center ex ante if the costs of adjustment are sufficiently large.

Steiner Distance in Product Networks [PDF]
Discrete Mathematics & Theoretical Computer Science, 2018 For a connected graph $G$ of order at least $2$ and $S\subseteq V(G)$, the \emph{Steiner distance} $d_G(S)$ among the vertices of $S$ is the minimum size among all connected subgraphs whose vertex sets contain $S$. Let $n$ and $k$ be two integers with $2\

On the variable hierarchy of first-order spectra
, 2015 The spectrum of a first-order logic sentence is the set of natural numbers that are cardinalities of its finite models. In this paper we study the hierarchy of first-order spectra based on the number of variables.

Inferring Lexicographically-Ordered Rewards from Preferences
Proceedings of the AAAI Conference on Artificial Intelligence, 2022 Modeling the preferences of agents over a set of alternatives is a principal concern in many areas. The dominant approach has been to find a single reward/utility function with the property that alternatives yielding higher rewards are preferred over alternatives yielding lower rewards. However, in many settings, preferences are based on multiple—often

International Transactions in Operational Research, EarlyView.Abstract This paper presents a two‐stage model for planning a renewable energy portfolio by balancing economic, social and environmental sustainability goals. The first stage addresses a multi‐objective problem where conflictive impacts generated by the energy portfolios should be optimised according to the corresponding economic, social or ...

Exact solution algorithms for biobjective mixed integer programming problems
International Transactions in Operational Research, EarlyView.Abstract We consider criterion space algorithms for biobjective mixed integer programs. The algorithms solve scalarization models in order to explore predetermined regions of the objective space called boxes, defined by two nondominated points. When exploring, the algorithm exploits information on its corner points and chooses the scalarization problem

Characterization of order-like dependencies with formal concept analysis [PDF]
, 2011 Functional Dependencies (FDs) play a key role in many fields of the relational database model, one of the most widely used database systems. FDs have also been applied in data analysis, data quality, knowl- edge discovery and the like, but in a very ...
