Well-Quasi-Orderings and the Robertson–Seymour Theorems

Part of the Texts in Computer Science book series (TCS)


As we will see, well-quasi-orderings (WQOs) provide a powerful engine for demonstrating that classes of problems are FPT. In the next section, we will look at the rudiments of the theory of WQOs, and in subsequent sections, we will examine applications to combinatorial problems.
