For Pakistan as of 2020-07-19, the best fit SEIR model is shown as:

Optimized SEIR model for the current corona virus evolution for Pakistan

Associated operational parameters:

\(S_0\) = 3.793854e+05 cases;

\(\beta\) = 2.566939e-06 (cases days)\(^{-1}\);

\(\sigma\) = 2.272716e-02 days\(^{-1}\);

\(\gamma\) = 3.807154e-02 days\(^{-1}\).

These translate into the more familiar parameters:

R = 25.579724;

T\(_{inc}\) = 44.000226 days;

T\(_{inf}\) = 26.266342 days.

The additional initial values were:

\(E_0\) = 2.00e+00, \(I_0\) = 2.00e+00, \(R_0\) = 0.00e+00.

As a measure of quality of the convergence of the annealing algorithm, the final error measure was:

\(\epsilon\) = 9.762238e+03 cases; with a relative error, \(\epsilon/S_0\) = 2.57e-02 or 2.6%
