The aim of this work is to use linear programming and polyhedral geometry to prove a duality formula for the ic-resurgence of edge ideals. We show that the ic-resurgence of the edge ideal I of a clutter C is equal to the ic-resurgence of the edge ideal I ∨ of the blocker C ∨ of C. We study the linear programs and the associated polyhedra that have been used to compute the ic-resurgence of squarefree monomial ideals. If C is a connected non-bipartite graph with a perfect matching or C is the clutter of bases of certain uniform matroids, we compute a formula for the ic-resurgence of I.
