A hybrid method for the modelling and optimisation of constrained search problems

Sitek, Pawel; Wikarek, Jaroslaw - In: Foundations of Management 5 (2013) 3, pp. 7-22

The paper presents a concept and the outline of the implementation of a hybrid approach to modelling and solving constrained problems. Two environments of mathematical programming (in particular, integer programming) and declarative programming (in particular, constraint logic programming) were...

Heuristic estimates in shortest path algorithms

Pijls, Pijls, W.H.L.M. - Faculteit der Economische Wetenschappen, Erasmus … - 2006

Shortest path problems occupy an important position in Operations Research as well as in Arti¯cial Intelligence. In this paper we study shortest path algorithms that exploit heuristic estimates. The well-known algorithms are put into one framework. Besides we present an interesting application...

Heuristic estimates in shortest path algorithms

Pijls, W.H.L.M. - Erasmus University Rotterdam, Econometric Institute - 2006

theory, Operations Research, Search problems. ⁄Econometric Institute, Erasmus University Rotterdam, P.O.Box 1738, 3000 DR …) addresses search problems involving heuristics estimates. The related algorithms can be viewed as shortest paths algorithms … availability of a so-called heuristic estimate. A heuristic estimate h is deflned as a function from V intoR. Many search problems …
