  +--de.tubs.cs.sc.casim.CAStatistics

public class CAStatistics

extends java.lang.Object

A class to analyse a CA using an internal Hashtable. State frequency will be counted and stored in a hastable to calculate different statistical values.

Constructor Summary

CAStatistics(de.tubs.cs.sc.casim.CellularAutomaton ca)
Constructor creates the hashtable call analyse to count the states

CAStatistics(de.tubs.cs.sc.casim.CellularAutomaton ca, boolean pairwise)
Constructor creates the hashtable call analyse to count the states

Method Summary

void	analyse() Clears the internal hash table and counts all states.
int	getNrOfAppearances(de.tubs.cs.sc.casim.State s)
int	getNrOfAppearances(java.lang.String s)
int	getNrOfCells()
int	getNrOfStates()
java.util.Enumeration	getStates()
boolean	isPairAnalysis() check if this object does pair analysis.
