Now we all know Graph matching is non-tractable but when degree of vertex has upper bound are there any tractable algorithm? Does this special case comes under 'Finite Parameter Tractability' ?

Hi.

There is currently another thread concerning search of graph isomorphism
using package "igraph". May be, you can learn something from there.
