Module criteria

source code

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 [hide private]
  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
