Implement the DES method to calculate the one$-$day$-$ahead forecasts for $3-$April$-2019$

to $15-$Aug$-2019.$ Use solver to determine the values of LS and TS that minimize the withinsample RMSE $($calculated based on the interval $8-$April$-2019$ to $15-$Aug$-2019),$ subject to the

constraint that LS and TS are between $0\mathrm{.}01$ and $0\mathrm{.}99.$ Report the following:

$(2$ pts$.$ feasibility, $1$ pt$.$ consistency, $2$ pts$.$ optimality$)$ Optimal values for LS$,$ TS$,$ and

the RMSE for $8-$April$-2019$ to $15-$Aug$-2019,$

$(7$ pts$.)$ Values of th
