Computer Science and Engineering Program (Autonomy) Paper WebACCEPT Introduction to DCFL and DPDA A DPDA is a PDA in which no state p has two different outgoing transitions ((p,x,α),(q,β)) and ((p,x,α ),(q,β )) which are compatible in the sense that both could be applied. A DCFL is basically a language which accepted by a DPDA, but we need to qualify this further.

WebAccording to the textbook's definition, a DPDA is a PDA in which no state p has two different outgoing transitions ((p,x,α),(q,β)) and ((p,x′,α′),(q′,β′)) which are compatible in the sense that both could be applied. A DCFL is basically a language which accepted by a DPDA, but we need to qualify this further.
