Method

class pylit.core.data_classes.Method(name, f, grad_f, solution, lr)

Bases: object

Represents a method for solving an optimization problem.

Parameters:

• name (str) – Name of the optimization method.

• f (callable) – The objective function to minimize.

• grad_f (callable) – Function computing the gradient of f.

• solution (callable) – Routine that computes the solution directly, without the non-negative constraint, if available.

• lr (callable) – Learning rate function that returns a step size, depending on the regression matrix R.
