WebApr 15, 2013 · The pseudocode. For each production R A → R B R C: if P [j,k,B] and P [j+k,i-k,C] then set P [j,i,A] = true. Should be interpreted in the following way. Suppose that it's the case that P [j, k, B] is true. That means that the string formed from k characters starting at position j can derived from the nonterminal R B. WebRecall our original rules for deductive parsing of context-free grammars. a : a D 1 [r]X! 1::: n w 1: 1::: w n: n w 1:::w n: X D 2 Interpreted as the CYK parsing algorithm, we allow these rules to be applied in any order or combination, so long as we only derive facts w: where wis a substring of the original string w 0 we are trying to parse.
