Detecting an infinite loop?

Question

Is there any way to detect an infinite loop in a function without resorting to monitoring the internal state of variables within the function?

Answer 1

Isn't this the Halting problem?

It is said to be an undecidable problem. :>

Answer 2

You can also - primitive but works - put a random print statement in there and look what happens.

Answer 3

You can set a timeout. then check and break the loop after specified duration.
