Figure 3: Optimality in sum total damage to the system while effecting arrest of pathological process is shown here. With increasing values the minimum in sum total damage to the system occurs at about the same value as the critical value at which the fraction of simulations in which the pathological process is arrested attains unity (cf. Figure 2(a)). This minimum occurs at higher values of with larger , and the minimum value also shifts upward. A similar situation occurs with different values (not shown here). Note that the -axis values have been taken at .
