Cyk membership algorithm

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.
