摘要
In this paper we study bounds on the density of oracles which can help to decrease the time-space complexity of recognition of a particular language by off-line multitape Turing machines. We establish an upper and a lower bound on the density of such oracles which are optimal up to a multiplicative constant and improve the bounds stated by Hromkovic (1991).
