Computational models

Definition

Computational models are abstract representations of systems that use mathematical and algorithmic processes to simulate the behavior of real-world phenomena. They serve as essential tools in various fields, allowing researchers to analyze, predict, and understand complex systems through computational methods, such as recursion. In the context of unbounded minimization and the μ-operator, these models help illustrate how functions can be defined and manipulated to find the least value of a given set of inputs.
