Interface ObjectiveFunction

All Known Implementing Classes:

StandardObjective

public interface ObjectiveFunction

Interface representing an optimization objective for multi-objective optimization.

An objective function evaluates a process system and returns a scalar value to be optimized (either maximized or minimized). Multiple objectives can be combined for Pareto optimization.

static enum	ObjectiveFunction.Direction	Direction of optimization.

Method Summary

Modifier and Type	Method	Description
static ObjectiveFunction	create(String name, ToDoubleFunction<ProcessSystem> evaluator, ObjectiveFunction.Direction direction, String unit)	Create a custom objective function.
double	evaluate(ProcessSystem process)	Evaluate the objective for the current process state.
default double	evaluateNormalized(ProcessSystem process)	Get normalized value for comparison (converts MINIMIZE to negative for consistent sorting).
ObjectiveFunction.Direction	getDirection()	Get the optimization direction.
String	getName()	Get the name of this objective for reporting.
String	getUnit()	Get the unit of the objective value for display.

Method Details

getName

String getName()

Get the name of this objective for reporting.

Returns:

objective name

getDirection

ObjectiveFunction.Direction getDirection()

Get the optimization direction.

Returns:

MAXIMIZE or MINIMIZE

evaluate

double evaluate(ProcessSystem process)

Evaluate the objective for the current process state.

Parameters:

process - the process system to evaluate

Returns:

the objective value

getUnit

String getUnit()

Get the unit of the objective value for display.

Returns:

unit string (e.g., "kW", "kg/hr", "%")

evaluateNormalized

default double evaluateNormalized(ProcessSystem process)

Get normalized value for comparison (converts MINIMIZE to negative for consistent sorting).

Parameters:

process - the process system to evaluate

Returns:

normalized value where higher is always better

create

static ObjectiveFunction create(String name,
 ToDoubleFunction<ProcessSystem> evaluator,
 ObjectiveFunction.Direction direction,
 String unit)

Create a custom objective function.

Parameters:

name - objective name

evaluator - function to evaluate the objective

direction - optimization direction

unit - unit string

Returns:

new ObjectiveFunction instance
