Constructor Summary

DiceEquation(double goal, int... dice)

Method Summary

double	calculate()
long	count()
boolean	getAllowRoot()
int[]	getDice()
double	getGoal()
boolean	gotoNext()
boolean	isSolution()
static void	main(String[] args)
boolean	nextSolution()
boolean	nextSolution(Monitor mon) some solutions returned hereby look the same as they falsely distinguish the order of dices; use printPath() to get a unique representatino
int	numberOfSolutions() should be performed only directly after construction or reset()
String	printPath()
void	reset()
void	setAllowRoot(boolean flag) should only be set before any other state is changed
static void	standardIteration(int goal, Writer writer) iterates through all combinations of the standard 5 dices and writes a tab-separated format along with the number of possible solutions for that combination for the given goal.
