Abstract
A method comprises obtaining temporal measurements associated with a heterogeneous material; building a numerical model of a material by assigning initial approximations to the temporal measurements; modifying the numerical model to create a modified numerical model; generating simulated temporal measurements associated with the temporal measurements using the modified numerical model; determining a reward, a penalty, or a modification based on a quality of a fit between the temporal measurements and the simulated temporal measurements; and updating the numerical model based on the reward, the penalty, or the modification.

- generating simulated temporal measurements using the numerical model;
- determining a reward or a penalty and determining a modification to the numerical model based on a quality of a fit between the temporal measurements and the simulated temporal measurements;
- updating the numerical model based on the modification;
- and
- iterating the updating based on the reward or the penalty and based on the modification until the quality of the fit is above a threshold.
