Algorithms and Programming
We will use the term “algorithm” rather loosely but always in the general sense of a method or a set of instructions for doing something. Formally, an “algorithm” must terminate. Sometimes we may describe an algorithm that may not terminate simply following steps in our description. Whether we expressly say so or not, there should always be a check on the number of steps, and the algorithm should terminate after some large number of steps no matter what. Algorithms are sometimes distinguished as “numerical”, “seminumerical”, and “nonnumerical”, depending on the extent to which operations on real numbers are simulated.
