Optimality criterion
In this article we will explore the impact of Optimality criterion on different aspects of modern society. Since its appearance on the public scene, Optimality criterion has generated great interest and debate among experts and citizens alike. Its influence has spread to various areas, from politics and economics to culture and entertainment. Over the next few lines, we will analyze in detail how Optimality criterion has changed the way we live, think and relate to each other.

In statistics, an optimality criterion[1] provides a measure of the fit of the data to a given hypothesis, to aid in model selection. A model is designated as the "best" of the candidate models if it gives the best value of an objective function measuring the degree of satisfaction of the criterion used to evaluate the alternative hypotheses.
The term has been used to identify the different criteria that are used to evaluate a phylogenetic tree. For example, in order to determine the best topology between two phylogenetic trees using the maximum likelihood optimality criterion, one would calculate the maximum likelihood score of each tree and choose the one that had the better score. However, different optimality criteria can select different hypotheses. In such circumstances caution should be exercised when making strong conclusions.
Many other disciplines use similar criteria or have specific measures geared toward the objectives of the field. Optimality criteria include maximum likelihood, Bayesian, maximum parsimony, sum of squared residuals, least absolute deviations, and many others.
