BreakingAlgorithm.BestRecords
public BreakingAlgorithm.BestRecords()
addRecord
public void addRecord(double demerits,
BreakingAlgorithm.KnuthNode node,
double adjust,
int availableShrink,
int availableStretch,
int difference,
int fitness)
- Registers the new best active node for the given fitness class.
- Parameters:
demerits
- the total demerits of the new optimal set of breakpointsnode
- the node starting the line ending at the current elementadjust
- adjustment ratio of the current lineavailableShrink
- how much the current line can be shrinkedavailableStretch
- how much the current line can be stretcheddifference
- difference between the width of the considered line and the
width of the "real" linefitness
- fitness class of the current line

- Parameters:
fitness
- fitness class (0, 1, 2 or 3, i.e. "tight" to "very loose")
- Returns:
- true if there is a set of feasible breakpoints registered for the
given fitness.
