Snippet: Using optimal control theory, we show that, assuming a quadratic cost for the control effort at a given time (c(t)), an optimal control strategy significantly reduces the number of deaths and is particularly sustainable at the population level. With this strategy, the intensity of the control increases rapidly over the first quarter of the time period to an intermediate value and then decreases steadily. Other strategies, such as implementing a s.....
Document: Using optimal control theory, we show that, assuming a quadratic cost for the control effort at a given time (c(t)), an optimal control strategy significantly reduces the number of deaths and is particularly sustainable at the population level. With this strategy, the intensity of the control increases rapidly over the first quarter of the time period to an intermediate value and then decreases steadily. Other strategies, such as implementing a strong short containment ("lock-down") followed by a looser and constant control effort are almost comparable to a strategy without control in terms of cumulative number of deaths. Indeed, in this constant control strategy, the epidemic peak is delayed but barely dampened.
