Quite clearly, there are many programs that can easily be shown to halt or go on forever The halting problem says that we cannot answer this question for all programs The reason for this is again the idea of self-reference To a practical person, the halting problem may not be of any immediate signi cance, but it has great theoretical importance as the dividing line between things that can be done on a computer (given unbounded memory and time) and things that cannot be done at all (such as proving all true statements in number theory) G del s incompleteness theorem is one of o the most important mathematical results of the twentieth century, and its consequences are still being explored The halting problem is an essential example of G del s incompleteness theorem.

o One of the consequences of the nonexistence of an algorithm for the halting problem is the noncomputability of Kolmogorov complexity The only way to nd the shortest program in general is to try all short programs and see which of them can do the job However, at any time some of the short programs may not have halted and there is no effective ( nite mechanical) way to tell whether or not they will halt and what they will print out Hence, there is no effective way to nd the shortest program to print a given string The noncomputability of Kolmogorov complexity is an example of the Berry paradox The Berry paradox asks for the shortest number not nameable in under 10 words A number like 1,101,121 cannot be a solution since the de ning expression itself is less than 10 words long.

Although the distance value is a straightforward measurement like a normal odometer, the angle value is an odometrical difference. Roomba has a distance sensor on each wheel, and the angle value in the sensor data is the difference in the distance traveled by each wheel. Specifically, it is the right wheel difference minus the left wheel difference. This difference describes a rotation around the center point between the two wheels. It s as if the wheels are moving partially along a circumference determined by the distance between the wheels. If this sounds a lot like that millimetersPerDegree stuff from 5, you re right. It s the same thing. The angle sensor value is a fraction of the entire number of millimeters per degree:
