    We study the following independent set reconfiguration problem: given two independent sets I and J of a graph G, both of size at least k, is it possible to transform I into J by adding and removing vertices one-by-one, while maintaining an independent set of size at least k throughout? This problem is known to be PSPACE-hard in general. For the case that G is a cograph on n vertices, we show that it can be solved in polynomial time. More generally, we show that for a graph class G that includes all chordal and claw-free graphs, the problem can be solved in polynomial time for graphs that can be obtained from a collection of graphs from G using disjoint union and complete join operations.
