Abstract

Greedy algorithms are one of the oldest known methods for code construction. They are simple to define and easy to implement, but require exponential running time. Codes obtained with greedy construction have very good encoding parameters; hence, the idea of finding faster algorithms for code generation seems natural. We start with an overview of the greedy algorithms and propose some improvements. Then, we study the code parameters of long greedy codes in attempt to produce stronger estimates. It is well known that greedy-code parameters give raise to the Gilbert-Varshamov bound; improving this bound is fundamental problem in coding theory.
