A blind mouse can smell a piece of cheese but can't see it. When the green flag is clicked the mouse's start position is randomly determined. The mouse then executes the algorithm. The mouse leaves a trail which shows that the algortimn typically generates a spiral path from the start position to the cheese.
One Blind Mouse — The mouse may not be able to see but makes up for it by having an extra-sensitive nose. The mouse can smell cheese and knows, as it taps its way along, whether the scent is getting stronger or weaker. The scent's strength is proportional to the mouse's distance from the cheese; the greater the distance, the weaker the scent. The mouse follows a simple algorithm: measure the distance (determine strength of cheese scent) to the wedge of cheese, move forward and measure scent level again (variable = seconddistance). If the scent is stronger (firstdistance<seconddistane) then turn left 40 degrees and move again. Repeat this move, test strength of scent, move again process, unti the wedge of cheese is found.
