Disease Spread in Coupled Populations: Minimizing Response Strategies Costs in Discrete Time Models
Figure 2
(a) The evolution of the worst case scenario, that is, when no control is applied, is shown in bullets () for susceptibles and infected classes in each patch. Using the parameter values found by the algorithm provides the scenario shown in (▲). (b) The total amount of infected individuals in both populations. Again, the worst case scenario is in () and the minimized results in (▲). The appearance of a second bump is due to the delay of introducing infective individuals in the initially disease-free population. (c) These are the strategy levels that minimize the total cost.
