Using techniques from differential game theory, we model the velociraptor) B, @& w t) v( U

By defining predator and prey behaviors in terms of **, intuitive principles,( u. `" {, I8 \2 ]
we identify a set of strategies designed to counter one another, such

strategies, in an essentially unpredictable, or protean, manner. The resulting
