class iwopy.core.optimizer.Optimizer

Bases: Base

Abstract base class for optimization solvers.

Parameters:

• problem (iwopy.Problem) – The problem to optimize

• name (str) – The name

problem

The problem to optimize

Type:

iwopy.Problem

name

The name

Type:

str

__init__(problem, name='optimizer')

Methods

__init__(problem[, name])
finalize(opt_results[, verbosity])	This function may be called after finishing the optimization.
initialize([verbosity])	Initialize the object.
print_info()	Print solver info, called before solving
solve([verbosity])	Run the optimization solver.

Attributes

initialized

Flag for finished initialization

__init__(problem, name='optimizer')

finalize(opt_results, verbosity=1)

This function may be called after finishing the optimization.

Parameters:

• opt_results (iwopy.OptResults) – The optimization results object

• verbosity (int) – The verbosity level, 0 = silent

initialize(verbosity=0)

Initialize the object.

Parameters:

verbosity (int) – The verbosity level, 0 = silent

property initialized

Flag for finished initialization

Returns:

True if initialization has been done

Return type:

bool

print_info()

Print solver info, called before solving

abstract solve(verbosity=1)

Run the optimization solver.

Parameters:

verbosity (int) – The verbosity level, 0 = silent

Returns:

results – The optimization results object

Return type:

iwopy.core.OptResults
