Parameter relations and their value changes from dual attack to Hybrid 1. An arrow “\(\rightarrow\)” (respectively, “\(\dashrightarrow\)”) from node A to node B means that increasing A will increase (respectively, decrease) B. “\(\uparrow\)” and “\(\downarrow\)” shows the direction that the values change from the dual attack to Hybrid 1 when r is increased and \(\beta\) is decreased while maintaining \(M \approx SV\) and \(N=1\) unchanged
