Minimum Feedback Vertex Sets in Distance Graphs and Circulant Graphs
For a set D⊂ Z n, the distance graph P n (D) has Z n as its vertex set and the edges are between vertices i and j with |i-j|∈D. The circulant graph C n (D) is defined analogously by considering operations modulo n. The minimum feedback vertex set problem consists in finding the small...
