Q1
The following two languages is the complement of a simpler language. Construct a DFA for the simpler
language, then use it to give the state diagram of a DFA for the langua
Claim 1: The Regular languages are closed under reverse.
Proof: Given a regular language A, show that the language AR is regular.
Since A is regular, there is a DFA M = Q, , , q0 , F that recognizes i
Polygon Triangulation
A polygonal curve is a nite chain of line segments. Line segments called edges, their endpoints called vertices. A simple polygon is a closed polygonal curve without self-inters
