WebThe Greedy method is the simplest and straightforward approach. It is not an algorithm, but it is a technique. The main function of this approach is that the decision is taken on the basis of the currently available information. Whatever the current information is present, the decision is made without worrying about the effect of the current ... WebOptimal Code Generation: Given an alphabet C and the probabilities p(x) of occurrence for each character x 2C, compute a pre x code T that minimizes the expected length of the encoded bit-string, B(T). There is an elegant greedy algorithm for nding such a code. It was invented in the 1950’s by David Hu man, and is called a Hu man code.
