Suppose that we are given two independent setsandof a graph such that, and imagine that a token is placed on each vertex in. Thetoken jumpingproblem is to determine whether there exists a sequence of independent sets of the same cardinality which transformsintoso that each independent set in the sequence results from the previous one by moving exactly one token to another vertex. This problem is known to be PSPACE-complete even for planar graphs of maximum degree three, and W[1]-hard for general graphs when parameterized by the number of tokens. In this paper, we present a fixed-parameter algorithm fortoken jumpingon planar graphs, where the parameter is only the number of tokens. Furthermore, the algorithm can be modified so that it finds a shortest sequence for a yes-instance. The same scheme of the algorithms can be applied to a wider class of graphs which forbid a complete bipartite graphas a subgraph for a fixed integer.
