Package com.graphhopper.jsprit.core.algorithm.ruin

Interface RuinOperatorFactory

public interface RuinOperatorFactory

Factory interface for creating ruin strategies.

This allows registering ruin operators with the algorithm builder without needing to pre-create all dependencies. The factory will be called during algorithm construction when all dependencies are available.

Example usage:

 Jsprit.Builder.newInstance(vrp)
     .addRuinOperator(0.3, Ruin.random(0.3))
     .addRuinOperator(0.3, Ruin.radial(0.3))
     .addRuinOperator(0.2, Ruin.cluster())
     .addRuinOperator(0.2, Ruin.kruskalCluster())
     .buildAlgorithm();

Method Details

create

RuinStrategy create(RuinOperatorFactory.Context context)

Creates a ruin strategy with the given dependencies.

Parameters:

context - the context containing all required dependencies

Returns:

the configured ruin strategy

getName

default String getName()

Returns the default name for this operator factory.

This name is used in strategy IDs when no explicit name is provided to addRuinOperator().

Returns:

the default name, or null if not specified

named

static RuinOperatorFactory named(String name,
 RuinOperatorFactory factory)

Creates a named factory wrapper.

Parameters:

name - the operator name

factory - the factory to wrap

Returns:

a factory that returns the given name from getName()
