constraint_tolerance

Maximum allowable constraint violation still considered feasible

## Specification

Alias: none

Argument(s): REAL

Default: Library default

## Description

Sets the maximum allowable value of infeasibility that any constraint in an optimization problem may possess and still be considered to be satisfied.

If a constraint's violation is greater than this value then it is considered to be violated by the optimization algorithm. This specification gives some control over how tightly the constraints will be satisfied at convergence of the algorithm. However, if the value is set too small the algorithm may terminate with one or more constraints being violated.

Dakota's `constraint_tolerance` settings maps to NPSOL's feasbility tolerance which is an absolute tolerance on the constraints.
