  • Abstract
    Two new models, NO-JAG and NN-JAG in order of increasing computation power, are introduced as extensions to the conventional JAG model. A space lower bound of Ω(log2 n/log log n) is proved for the problem of directed st-connectivity on a probabilistic NN-JAG and a space upper bound of O(log n) is proved for the problem of directed st-nonconnectivity on a nondeterministic NO-JAG. It is also shown that a nondeterministic NO-JAG is nearly as powerful as a nondeterministic Turing machine
