 class BruteForceGenerator
extends Generator

This class contains the N digit number game guess Generator that uses the Brute Force algorithm.

For each next guess it simply goes through a sequence of valid numbers to find one that could have given all of the scores that were obtained for the previous guesses.

Constructor Summary

BruteForceGenerator()
constructs a BruteForceGenerator

Method Summary

static void	main(java.lang.String[] arg) tests the class
boolean	nextGuess(Numbah guess) generates the next guess
void	retractScore() backs up to state before last nextGuess()
void	tellScore(Score score) is given a score for the last guess

true iff there is a next guess. (It won't be possible to generate a guess if scores given for the previous guesses are logically inconsistent.)

tellScore

public void tellScore(Score score)

is given a score for the last guess

Specified by:

tellScore in class Generator

Parameters:

score - the score for the last guess

retractScore

public void retractScore()

backs up to state before last nextGuess()

Specified by:

retractScore in class Generator

main
