The fraction of susceptible nodes saved from infection under the optimal partition (solid line) and the QCQP approach (dashed line) in Erdős-Renyi random graphs, as a function of the link probability p and for different link removal constraints K. The performance bound derived from the SDP is shown for each case (dotted line). Evaluated over 5,000 random networks of 15 nodes with 5 infected nodes.
