Given a graphG= (V,E), two verticess,t∈V, and two integersk,ℓ, theShort Secluded Pathproblem is to find a simples‐t‐path with at mostkvertices andℓneighbors. We study the parameterized complexity of the problem with respect to four structural graph parameters: the vertex cover number, treewidth, feedback vertex number, and feedback edge number. In particular, we completely settle the question of the existence of problem kernels with size polynomial in these parameters and their combinations withkandℓ. We also obtain a 2O(tw)· ℓ2·n‐time algorithm forn‐vertex graphs of treewidth tw, which yields subexponential‐time algorithms in several graph classes.
