In this paper a genetic algorithm for solving timetable scheduling problem is described. The algorithm was tested on small and large instances of the problem. Algorithm performance was significantly enhanced with modification of basic genetic operators, which restrain the creation of new conflicts in the individual.
Adaptive hypermedia courseware systems resolve the problem of users' disorientation in hyperspace through the adaptive navigation and presentation support. We describe the AHyCo (Adaptive Hypermedia Courseware) — an adaptive Web-based educational system for creation and reuse of adaptive courseware with emphasis on adaptive navigation support and lessons… (More)
An application generator has resulted from the authors' efforts to improve the development of interactive database applications. The developed tool is based on a meta-base. The meta-base comprises an extended data model, the programming language description and some additional information to support the generation process. The procedures described in a… (More)
A web-based information system for management of scientific electronic journals is presented in the paper. Journal management requires exchange of information between many participants in the publishing process, including authors, reviewers, editors, and lectors. Each participant in the process plays a different role, and cooperates with other participants.… (More)
While using the Web-based hypermedia courseware the students need navigational help to find their way through the learning material. Otherwise, they could get " lost in hyperspace ". In this paper we describe our approach developing Web-based adaptive educational hypermedia systems (AEHS) with the emphasis on adaptive navigation support. Our goal is to… (More)
Deployment of e-Invoice infrastructure promises great savings in business transactions costs.
