                     StandardOptimizerModifying

A standard optimizer, takes a step and finds the best candidate Must give in self.optimalPoint the optimal point after optimization After each iteration the resulting optimization point is modified by a call to a function

Method Details

[hide private]

init(self, **kwargs)
(Constructor)

source code

Needs to have :

an object function to optimize (function), alternatively a function ('fun'), gradient ('gradient'), ...
a way to get a new point, that is a step (step)
a criterion to stop the optimization (criterion)
a starting point (x0)
a way to find the best point on a line (line_search)

Can have :

a step modifier, a factor to modulate the step (step_size = 1.)
a pre-modifier, that acts on the set of parameters before an iteration (pre_modifier)
a post-modifier, that acts on the set of parameters after an iteration (post_modifier)

Overrides: object.__init__

iterate(self)

source code

Implementation of the optimization. Does one iteration

Overrides: optimizer.Optimizer.iterate
