Reducing computational effort in field optimisation problems

Reducing Testing Effort using Automation

Software quality is a major concern in the development of modern software systems. Software testing is the process of putting the developed system under testing to ensure its high quality. Unfortunately, software testing process is expensive and consumes a lot of time through software development life cycle. As software systems grow, manual software testing becomes more and more difficult espec...

Reducing Articulatory Effort in Non-word Tokens

SUMMARY English Speech sounds in high-frequency words are more likely to be reduced than speech sounds in low-frequency words, due to greater application of phonological processes in highly frequent words. Here, the tendency of Danish speakers to lenite intervocalic /t d/ in non-words was tested in different morphological environments, to examine whether this effect also applies to new words af...

Applying Extremal Optimisation To Dynamic Optimisation Problems

Uncertain Constraint Optimisation Problems

Data uncertainties are inherent in the real world. The uncertain CSP (UCSP) is an extension of classical CSP that models incomplete and erroneous data by coefficients in the constraints whose values are unknown but bounded, for instance by an interval. It resolution is a closure, a set of potential solutions. This paper extends the UCSP model to account for optimisation criteria, by defining th...

Some optimisation problems revisited

We consider some simple optimisation problems and employ a non-traditional method to solve them. We try to model both the problem and solution domains as algebraic structures, attempting to characterise the join operations on these domains. In each of the examples chosen, these structures turn out to be monoids and we make use of the homomorphisms between the problem and solution structures to ...
