Abstract Function¶

AbstractFunction¶

class disropt.functions.abstract_function.AbstractFunction[source]¶

AbstractFunction class. This should be the parent of all specific (objective) functions.

input_shape¶

shape of the input of the function

output_shape¶

shape of the output of the function

differentiable¶

True if the function is differentiable

affine¶

True if the function is affine

quadratic¶

True if the function is quadratic

Evaluate the function at a point x

jacobian(x, **kwargs)[source]¶

Evaluate the jacobian of the the function at a point x

subgradient(x, **kwargs)[source]¶

Evaluate the subgradient of the function at a point x

Parameters: x (ndarray) – input point
Raises: ValueError – subgradient is defined only for functions with scalar output
Return type: ndarray

hessian(x, **kwargs)[source]¶

Evaluate the hessian of the the function at a point x
