Heuristics.

Explanation:

Heuristics (also called “mental shortcuts” or “rules of thumb") are efficient mental shortcuts, simple strategies, which allow people to solve problems, learn new concepts, and make judgments quickly and efficiently. These processes make problems less complex by ignoring some of the information that’s coming into the brain, either consciously or unconsciously. These rule-of-thumb strategies shorten decision-making time and allow people to function without constantly stopping to think about their next course of action. Heuristics are helpful in many situations, but they can also lead to cognitive biases.

Heuristics

Explanation:

The problem-solving method used is heuristics was a science that had to do with logic, psychology or philosophy. It aims to discover the solution of a given problem; therefore, it is not something definitive and does not have to be rigorous, but it is something provisional and should not be confused with the mathematical proof.
