Module criteria

A list of standard convergence criteria based on the number of iterations, the last values taken by the cost function and the associated points

Classes

IterationCriterion
A simple criterion that stops when the iteration limit is reached

MonotonyCriterion
A simple criterion that stops when the values of the function starts to rise again

RelativeValueCriterion
The relative criterion stops the optimization when the relative error of the value is below a certain level (ftol)

AbsoluteValueCriterion
The absolute criterion stops the optimization when the absolute error of the value is below a certain level (ftol)

RelativeParametersCriterion
The relative criterion stops the optimization when the relative error of the parameters is below a certain level (xtol)

AbsoluteParametersCriterion
The absolute criterion stops the optimization when the relative error of the parameters is below a certain level (xtol)

GradientCriterion
The gradient criterion stops the optimization when the gradient at the current point is less that a given tolerance
