We show that optimal partisan redistricting with geographical constraints is a computationally intractable (NP-complete) problem. In particular, even when voter's preferences are deterministic, a solution is generally not obtained by concentrating opponent's supporters in \unwinnable" districts...

In the context of discrete districting problems with geographical constraints, we demonstrate that determining an (ex post) unbiased districting, which requires that the number of representatives of a party should be proportional to its share of votes, turns out to be a computationally...

A cikk bevezetést nyújt az időben változó együtthatójú lineáris ökonometriai modellek megoldási módozataiba és elemzi ökonometriai képességeiket. Elsőként az állapot-tér modellkeretben működő Kalman-szűrőt és a hozzá szorosan kapcsolódó (ám kevéssé ismert)...

Bármennyire szeretne is egy bank (vállalat, biztosító) csak az üzletre koncentrálni, nem térhet ki a pénzügyi (hitel-, piaci, operációs, egyéb) kockázatok elől, amelyeket mérnie és fedeznie kell. A teljes fedezés vagy nagyon költséges, vagy nem is lehetséges, így a csőd...

The aim of this paper is to survey the game theory modelling of the behaviour of global players in mitigation and adaptation related to climate change. Three main fields are applied for the specific aspects of temperature rise: behaviour games, CPR problem and negotiation games. The game theory...

This is a follow up to "Solution of the least squares method problem of pairwise comparisons matrix" by Bozóki published by this journal in 2008. Familiarity with this paper is essential and assumed. For lower inconsistency and decreased accuracy, our proposed solutions run in seconds instead...

The paper studies a generalisation of the dynamic Leontief input-output model. The standard dynamic Leontief model will be extended with the balance equation of renewable resources. The renewable stocks will increase regenerating and decrease exploiting primary natural resources. In this study...
