WebWe can use this property to find the center of any given circle. Example: Determine the center of the following circle. Solution: Step 1: Draw 2 non-parallel chords. Step 2: Construct perpendicular bisectors for both the chords. The center of the circle is the point of intersection of the perpendicular bisectors. WebAlgorithmic complexity. Spinrad (1994) gives an O(n 2)-time algorithm that tests whether a given n-vertex undirected graph is a circle graph and, if it is, constructs a set of chords that represents it. A number of other problems that are NP-complete on general graphs have polynomial time algorithms when restricted to circle graphs. For instance, Kloks (1996) … cindy\u0027s blinds gresham
