# Hypothesis evaluation functions

> FlexiLayout functions for computing penalty coefficients that adjust hypothesis quality during element evaluation in Extraction Rules activities.

| Function | Description |
| :- | :- |
| `Quality FuzzyQuality( Area value, AreaFuzzyInterval interval )` | Specifies a function for computing a penalty coefficient by which the quality of a hypothesis for the element should be multiplied. The function is calculated as the result of checking if the value "value" belongs to the fuzzy interval "interval." |
| `Quality FuzzyQuality( DistInterval value, DistFuzzyInterval interval )` | The function calculates the penalty coefficient by which the quality of the element hypothesis must be multiplied. The function checks whether the value "value" belongs to the fuzzy interval "interval." |
| `Quality FuzzyQuality( Int value, IntFuzzyInterval interval )` | The function calculates the penalty coefficient by which the quality of the element hypothesis must be multiplied. The function checks whether the value "value" belongs to the fuzzy interval "interval." |
| `Quality Quality( Real )` | Sets the penalty coefficient by which the quality of the element hypothesis must be multiplied. |
