We present here the proof for an alternative procedure to convert a Push Down Automata (PDA) into a Context Free Grammar (CFG). The procedure involves intermediate conversion to a single state PDA. In view of the authors, this conversion is conceptually intuitive and can serve as a teaching aid for the relevant topics.
The multi-hour bandwidth packing problem arises in telecommunication networks that spans several time horizon. The problem seeks to select and route a set of messages from a given list of messages with prespecified requirement on demand for band-width under time varying traffic conditions on an undirected communication network such that the total profit is… (More)
Developments in semantic web technologies have promoted ontological encoding of knowledge from diverse domains. However , modelling many practical domains requires more expressive representations schemes than what the standard description logics(DLs) support. We extend the DL SROIQ with constraint networks and grounded circumscription. Applications of… (More)
