ScipyOptimizerResult

Bases: OptimizerResult

Represents the optimization result for scipy optimize algorithms

Notes

``OptimizeResult`` may have additional attributes not listed here depending
on the specific solver being used. Since this class is essentially a
subclass of dict with attribute accessors, one can see which
attributes are available using the `OptimizeResult.keys` method.
