class desdeo_tools.solver.ScalarMinimizer(scalarizer, bounds, constraint_evaluator=None, method=None)

Bases: object

Implements a class for minimizing scalar valued functions with bounds set for the variables, and constraints.

Methods Summary

get_presets()	Return the list of preset minimizers available.
minimize(x0)	Minimizes the scalarizer given an initial guess x0.

Methods Documentation

get_presets()

Return the list of preset minimizers available.

minimize(x0)

Minimizes the scalarizer given an initial guess x0.

Parameters

x0 (np.ndarray) – A numpy array containing an initial guess of variable values.

Returns

A dictionary with at least the following entries: ‘x’ indicating the optimal variables found, ‘fun’ the optimal value of the optimized function, and ‘success’ a boolean indicating whether the optimizaton was conducted successfully.
