The subject of the research activities of the centre are methods, algorithms, and structures of theoretical computer science, and their applications in information technologies, e.g. in the issue of large networks (WWW), in issues of the security, reliability, and optimization of specific problems. Selected properties of discrete, geometric, and random structures will be studied, where the selection is based on their relevance or direct applicability to the development of new methods and algorithms in the area of information technologies and global networks. In all of these fields, the research team has the prerequisities for succesfull work and leadership, for it embodies the international recognized scientists and the young resercher and graduated students as well, who have also the generation prerequisities for the succesful research results transfer to applications. In its entirety it is a unique project on the European scale.
