In 2000 Alber et al. [ SWAT 2000] obtained the first parameterized subexponential algorith m on undirected planar graphs by showing that k-DOMINATING SET is solvable in time2O( √ k)nO(1), wheren is the input size. This result triggered an extensive study o f parameterized problems on planar and more general classes of sparse graphs and culmina ted the creation of Bidimensionality Theory by Demaine et al. [ J. ACM 2005]. The theory utilizes deep theorems from Graph Minor Theory of Robertson and… CONTINUE READING
