A note on “Multicriteria adaptive paths in stochastic, time-varying networks”
Pretolani, Daniele; Nielsen, Lars Relund; Andersen, Kim … - Ehrvervøkonomisk Institut, Institut for Økonomi - 2006
In a recent paper, Opasanon and Miller-Hooks study multicriteria adaptive paths in <p> stochastic time-varying networks. They propose a label correcting algorithm for finding the full set of efficient strategies. In this note we show that their algorithm is not correct, since it is based on a...</p>

The Efficiency of the Japanese Equity Market
Nagayasu, Jun - International Monetary Fund (IMF) - 2003
Using the ARFIMA-FIGARCH model, this paper studies the efficiency of the Japanese equity market by examining the statistical properties of the return and volatility of the Nikkei 225. It shows that both follow a long range dependence, which stands against the efficient market hypothesis (EMH)....

Operations research supports container handling
Meersmans, P.J.M.; Dekker, R. - Erasmus University Rotterdam, Econometric Institute - 2001
In this paper we will give an overview of the use of operations research models and methods in the design and operation of container terminals. We will describe the activities that take place at a container terminal and give an overview of the relevant decision problems, both at a strategic,...

Bidirectional A*: comparing balanced and symmetric heuristic methods
Post, H.; Pijls, W.H.L.M. - Erasmus University Rotterdam, Econometric Institute - 2006
A widely known algorithm for ¯nding the shortest path in a network is Bidirectional A*. The version of bidirectional A* that is considered the most appropriate hitherto, uses so-called balanced heuristic estimates. In this paper, we focus on symmetric heuristic estimates. First, we show that...

Automatic Term Identification for Bibliometric Mapping
Eck, N.J.P. van; Waltman, L.R.; Noyons, E.C.M.; Buter, R.K. - Erasmus Research Institute of Management (ERIM), ERIM … - 2008
A term map is a map that visualizes the structure of a scientific field by showing the relations between important terms in the field. The terms shown in a term map are usually selected manually with the help of domain experts. Manual term selection has the disadvantages of being subjective and...
