$3.(1$ pt$.$ feasibility, $3$ pts$.$ consistency, $1$ pt$.$ optimality$)$ Use the DES method to calculate the one

month$-$ahead forecasts for January $2016$ to December $2022.$ Use solver to find the values of LS

and TS that minimize the RMSE for January $2016$ to December $2022.$ Keep LS and TS in the

range $0\mathrm{.}05$ to $0\mathrm{.}95.$ Report the following:

$$ LS$,$ TS

$$ RMSE for January $2016$ to December $2022$

$$ Forecasts for January $2021$ to December $2022$

$$ RMSE for January $2021$ to December $2022$
