Method Detail

mutate

public boolean mutate(TrajectoryFitness parent,
                      ThreadContext context)

Description copied from interface: IMutation

Based on the parent solution, it creates one child solution by leaving the DSE in the child solution's state (model and trajectory is reachable via the context). If the child generation was unsuccessful, it backtracks to the initial model: leaving the state with an empty trajectory.

Specified by:

mutate in interface IMutation

Parameters:

parent - The parent solution (trajectory)

context - Context of the design space exploration

Returns:

True if the child generation was successful and the context is in the child's state.

createNew

public IMutation createNew()

Description copied from interface: IMutation

Creates a new instance. Required for multi-threaded execution. Can return the same instance (e.g. this) if the implementation is stateless.

Specified by:

createNew in interface IMutation

Returns:

An instance.
