Improvement of Prescriptors over time. The Prescriptors from the Pareto fronts on June 9th, July 4th, and July 28th were run for 180 days from July 28th against the Predictor from July 28th. The later Prescriptors are closer to the bottom left corner, indicating that when evolved with more experienced Predictors, they minimize cases and stringency better. The prescription profiles also change, suggesting that different NPI strategies are needed at different stages of the pandemic.
