Competence-based approaches in the field of formal or non-formal education and training are becoming more common and appear to offer the opportunity to develop programmes that mee...

The availability of programmable hardware devices with high density of logic elements and the possibility of implementing CPUs (called softcores) using a fraction of the FPGA area...
Software is increasingly pervasive in the products we use. Consequently, more programmers are needed to develop the software, and consequently there is unmet demand on programming...
In this paper we argue that an attractive and potentially very general way of achieving generalized arc consistency (GAC) on a constraint is by using unit propagation (UP) over a C...
