KeyPlayer is a program for identifying an optimal set of nodes in a network for one of two basic purposes: (a) crippling the network by removing key nodes, and (b) selecting which nodes to either keep under surveillance or to try to influence via some kind of intervention. The two purposes are different and require different procedures. KeyPlayer 1.4 provides two approaches for the first goal, and one approach for the second.
