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

Optimized SEIR model for the current corona virus evolution for Mexico

Associated operational parameters:

\(S_0\) = 1.274658e+06 cases;

\(\beta\) = 4.692001e-05 (cases days)\(^{-1}\);

\(\sigma\) = 9.737057e-04 days\(^{-1}\);

\(\gamma\) = 1.492615e-01 days\(^{-1}\).

These translate into the more familiar parameters:

R = 400.685762;

T\(_{inc}\) = 1027.004370 days;

T\(_{inf}\) = 6.699652 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:

\(\epsilon\) = 1.167626e+03 cases; with a relative error, \(\epsilon/S_0\) = 9.16e-04 or 0.1%
