iteration

public boolean iteration(GeneralTask task)
                  throws SolverException

Iterates the swarm.

Specified by:

iteration in class PathOptimiser

Parameters:

task - a SearchTask that needs to be driven to a minimum of SSR.

Returns:

the SSR value with the newly found parameters.

Throws:

SolverException

prepare

public void prepare(GeneralTask task)
             throws SolverException

Description copied from class: PathOptimiser

Defines a set of procedures to be run at the end of the search iteration.

Specified by:

prepare in class PathOptimiser

Parameters:

task - the SearchTask undergoing optimisation

Throws:

SolverException

initState

public IterativeState initState(GeneralTask t)

Description copied from class: PathOptimiser

Creates a new Path suitable for this PathSolver

Specified by:

initState in class PathOptimiser

Parameters:

t - the task, the optimisation path of which will be tracked

Returns:

a Path instance

compatibleWith

public boolean compatibleWith(OptimiserStatistic os)

Description copied from class: PathOptimiser

Checks if this optimiser is compatible with the statistic passed to the method as its argument.By default, this will accept any OptimiserStatistic

Overrides:

compatibleWith in class PathOptimiser

Parameters:

os - a selected optimiser metric

Returns:

true, if not specified otherwise by its subclass implementation.
