Résumé:
We consider a set V of elements and an optimization problem on V : the
search for a maximum (or minimum) cardinality subset of V verifying a given
property P. A d-transversal is a subset of V which intersects any optimum
solution in at least d elements while a d-blocker is a subset of V whose removal
deteriorates the value of an optimum solution by at least d. We present some
general characteristics of these problems, we review some situations which
have been studied (matchings, s
.
t paths and s
.
t cuts in graphs) and we
study d-transversals and d-blockers for new problems as stable sets or vertex
covers in bipartite graphs.
Keywords: transversal, blocker, cover, bipartite graph, matching,
s.
t path,
s
.
t cut, stable set, bilevel programming.
