Summary

Class to implement adaptive stepsize.

Extended Summary

This class wraps the step taking class and modifies the stepsize to ensure the true acceptance rate is as close as possible to the target.

Parameters

takestep : callable: The step taking routine. Must contain modifiable attribute takestep.stepsize
accept_rate : float, optional: The target step acceptance rate
interval : int, optional: Interval for how often to update the stepsize
factor : float, optional: The step size is multiplied or divided by this factor upon each update.
verbose : bool, optional: Print information about each update
