Abstract
In the first part of this paper a slow parallel recognizer is described for general CFG’s. The recognizer runs in 𝛩(n3/p(n)) time with p(n) = O(n2) processors. It generalizes the items of the Earley algorithm to double dotted items, which are more suited to parallel parsing. In the second part a fast parallel recognizer is given for general CFG’s. The recognizer runs in O(log n) time using O(n6) processors. It is a generalisation of the Gibbons and Rytter algorithm for grammars in CNF.- Anthology ID:
