We apply competitive analysis onto the problem of minimizing the number of queries to an oracle to completely reconstruct a given monotone Boolean function. Besides lower and upper bounds on the competitivity we determine optimal deterministic online algorithms for the smallest problem instances.

The research suggests that Chinese companies do not subscribe to ‘western’ strategy theory. As they rapidly internationalise through massive Foreign Direct Investment, Chinese companies are developing new perspectives on achieving competitiveness. A comparison of the Resource-Based View of strategy (RBV) constructs from western literature with identified (indigent) Chinese business strategies f...

This paper summarizes the main areas of research within TA Weinberg, namely an investigation into code review ability and personality; an investigation into code comprehension and personality; and an investigation into the results from an online programming competition and personality. With regard to code review, it was discovered that there is a relationship between code review ability and per...

This paper presents a case study where competitive e-learning strategies are used in the teaching of an undergraduate Database course in order to develop, in university students, the capacity to actively research and to lead their own learning process. The experience has been carried out in the spring semester (February-June 2007) and is based on the use of the QUEST system. This tool for activ...

Five methods that generate multiple prototypes from labeled data are reviewed. Then we introduce a new sixth approach, which is a modification of Chang’s method. We compare the six methods with two standard classifier designs: the 1nearest prototype (1-np) and 1-nearest neighbor (1-nn) rules. The standard of comparison is the resubstitution error rate; the data used are the Iris data. Our modif...

This paper describes a study of a simple open learner model that can be optionally released to peers in named or anonymous form, to facilitate collaborative and competitive learning in a situation where the learner model contents contributed to students' assessment. Results suggest that, under the right conditions, students may start working sooner; discussion amongst students can be increased;...
