    Notes: Abstract The problems of gossiping and broadcasting in one-way communication mode are considered for some prominent families of graphs. The complexity is measured as the number of communication rounds in the gossip and broadcast algorithms. The main result of the paper is the precise estimation of the gossip-problem complexity in cycles. To obtain this result a new combinatorial analysis of gossiping in cycles is developed. This analysis leads to an optimal lower bound on the number of rounds, and also to the design of an optimal algorithm for gossiping in cycles. The optimal algorithm for gossiping is later used to design new, effective algorithms for gossiping in important families of interconnection networks (cube connected cycles, butterfly networks). Furthermore, a new, effective algorithm for broadcasting in shuffle-exchange networks is developed.

    Notes: Abstract It is shown that for some languages no oracle (or only oracles with exponential density—depending on the way in which the space complexity in oracle computations is measured) can help to decrease their time-space complexity. This result is shown to be to some extent independent of the machine model used (single-tape, multitape, or multihead Turing machines, RAMs, etc.) Further, a new complexity measure reflecting the amount of information provided by an oracle for language recognition is introduced. The tradeoff of this measure and time-space complexity is discussed.
