CL - 15a - Regular Languages (III) : DFA-regular

Our third definition: we say a language is DFA-regular if it is the language recognised by some DFA.We show that the complement of a DFA-regular language is DFA-regular.

CL - 14e - DFA (II)

We look at the representation of DFA in Haskell (using lists to represent the sets of the formal definition).In this video the code isDFA is defining what counts as a DFA when we use the black-hole…

CL - 14d - Regular Languages (II)

We give a second definition of regular language as the languages generated from the empty and singleton languages by the operations of, concatenation, alternation, and iteration.

CL - 13d - Black holes and DFA

We begin with a short discussion of the history and some applications of FSM. We then introduce Deterministic Finit-state Automata (DFA), and the use of the black hole convention when presenting…
