Solver configuration

Definition

Solver configuration refers to the settings and parameters that define how an optimization solver operates when attempting to find a solution to a mathematical problem. This includes selecting algorithms, setting tolerances, defining variable bounds, and specifying output options, which collectively influence the efficiency and effectiveness of the optimization process.
