 double improvement_rate_coefficient,
 int improvement_rate_solutions_distance)

Method Details

getCPtr

protected static long getCPtr(ImprovementSearchLimit obj)

finalize

protected void finalize()

Overrides:

finalize in class SearchLimit

delete

public void delete()

Overrides:

delete in class SearchLimit

copy

public void copy(SearchLimit limit)

Description copied from class: SearchLimit

Copy a limit. Warning: leads to a direct (no check) downcasting of 'limit'
so one needs to be sure both SearchLimits are of the same type.

Overrides:

copy in class SearchLimit

makeClone

public SearchLimit makeClone()

Description copied from class: SearchLimit

Allocates a clone of the limit.

Overrides:

makeClone in class SearchLimit

check

public boolean check()

Description copied from class: SearchLimit

This method is called to check the status of the limit. A return
value of true indicates that we have indeed crossed the limit. In
that case, this method will not be called again and the remaining
search will be discarded.

Overrides:

check in class SearchLimit

atSolution

public boolean atSolution()

Description copied from class: SearchMonitor

This method is called when a valid solution is found. If the
return value is true, then search will resume after. If the result
is false, then search will stop there.

Overrides:

atSolution in class SearchMonitor

init

public void init()

Description copied from class: SearchLimit

This method is called when the search limit is initialized.

Overrides:

init in class SearchLimit
