Web14 de abr. de 2015 · Our hierarchy theorem says that for every , there is an explicit -variable Boolean function , computed by a linear-size depth- formula, which is such that any depth- circuit that agrees with on fraction of all inputs must have size This answers an open question posed by Håstad in his Ph.D. thesis. WebThe Space Hierarchy Theorem states that If f ( n) is space contructible, then for any g ( n) ∈ o ( f ( n)) we have S P A C E ( f ( n)) ≠ S P A C E ( g ( n)) An example of a SHT proof can be found here or here but they are generally based on the same idea differing only in technical details. We would like to find a language L such that

Web20 de abr. de 2024 · Download PDF Abstract: The celebrated Time Hierarchy Theorem for Turing machines states, informally, that more problems can be solved given more time. The extent to which a time hierarchy-type theorem holds in the distributed LOCAL model has been open for many years. It is consistent with previous results that all natural problems … WebIt is easy to show (by probabilistic argument) that there exist functions that require circuits of size O ( 2 n / n). This, in turn, can be used to prove a non-deterministic hierarchy theorem showing (roughly) that if 2 n / n > T ( n) ≫ t ( n) then there exist functions that can be computed by circuits of size T but not by circuits of size t. good names for popular girls
