Symp. on Theoretical Aspect of Computer Science, STACS, in: Lecture Notes in Computer Science, vol. 1563, 1999, pp. 173â 183] to provide a simpler proof, and a faster algorithm … Webof G. A branch decomposition of Gwith width equal to the branchwidth is an optimal branchdecompositionof G. Figure 2 illustrates an optimal branch decomposition of the graph given in Figure 1. Robertson and Seymour [106] characterized the graphs which have branchwidth ≤ 2 and showed that n× n-grid graphs have branchwidth n.
