Before revision:  It assumes that attractors  correspond to phenotypes produced by the modeled biological network. It identifies target combinations which allow disturbed networks to avoid attractors associated with pathological phenotypes.
After revision:  It assumes that attractors correspond to phenotypes produced by the modeled biological system. Under this assumption, and given a Boolean network modeling a pathophysiology, the algorithm identifies target combinations which allow disturbed networks to avoid attractors associated with pathological phenotypes.
