Community Web Portals (e.g., digital libraries, vertical aggregators, infomediaries) have become quite popular nowadays in supporting specific communities of interest on corporate...
We study probabilistic complexity classes and questions of derandomisation from a logical point of view. For each logic L we introduce a new logic BPL, bounded error probabilistic ...
