WebA DPDA can be designed for reverse(L1) also. Likewise, a DPDA can be designed for L2. However, as discussed in Section 8.1.4, reverse(L2) is not a DCFL, as it is impossible to keep both decisions – whether j = k or k = m – ready by the time i is encountered. L3 is not a CFL at all. However, L4, the complement of L3, is a CFL.

WebJan 1, 2014 · The class of deterministic context free languages (DCFL) contains the class of regular languages, and DCFL can be represented by deterministic pushdown automata (DPDA). It was shown by Sreenivas (1993) and Masopust (2012) that step (i) of the fixed point algorithm to calculate Lclm cannot be realized for the case where both the plant … WebDeterministic Push Down Automata for a^n-b^n-c^m-d^m. DPDA for anbncmdm n,m≥1. Just see the given problem in another perspective. Number of a's are equal to number of b's. And number of c's are equal to number of d's. That we will achieve by pushing a's and poping a's for every b. And then pushing c's and poping c's for every d's.
