Bug 687

Bug is confirmed

The bug is fixed. There is a mistake on line 91 in the Solver.java. Replace roles with role.

Modification of code:

	public ArrayList<Move> getLegalMoves(Puzzle puzzle, Node currState) {
		ArrayList<Move> moves = new ArrayList<Move>();
		
		RuleSet ruleSet = new RuleSet(puzzle);
		HashSet<String> travelables = puzzle.getTravelables();
		
		PuzzleState puzzleState = currState.getPuzzleState();
		
		
		int origin = puzzleState.getBoatPos();
		int dest = (origin==0)?1:0;
		
		ArrayList<String> roles = puzzleState.getLandByID(origin);
		
		
		//one traveler 
		for(String travler : travelables)
		{
				Move move = new Move(travler,null, origin, dest);
				Response res = ruleSet.isValidMove(puzzleState, move);
				if (res.isValid())
					moves.add(move);
		}
		
		//two travelers
		for(String travler : travelables)
		{
			for(String role : roles)
			{
				if(travler.equals(role))
					continue;
				
				Move move = new Move(travler,role, origin, dest);
				Response res = ruleSet.isValidMove(puzzleState, move);
				if (res.isValid())
					moves.add(move);
			}
		}

					
		return moves;
	}
