D.Sc. Emerson Lamb Moral. Belm 2010 1. INTRODUCTION Before approaching thematic ' ' Techniques of analyses and projects of algorithms applied to bioinformtica' ' it is needed to have in mind, first, the concept of the word algorithm. Etimologicamente the word algorithm originates from the Al-Khwarizmi last name, of a Persian mathematical celebrity of century IX Mohamed call well Muse.

However some scholars affirm that the word originates from the Al-Goreten term. Conceptually, for CASTIEIRA, in the workmanship ' ' Analysis of Algoritmos' ' , it is understood algorithm as a finite and commanded sequncia of necessary procedures for the resolution of a problematic one formulated, possible well of being applied in computer, that always finishes in one definitive period of time, producing the result or indicating the impossibility of attainment of the same. The algorithm concept is used in practically all the areas of the knowledge, only changing the nomenclature in validity. For example, ' is cited; ' Plan of Ao' ' frequent used in areas as the administration and the accounting that nothing more is of what a set of solutions for one determined problem, aiming at to get a satisfactory result, that is, an algorithm. In the material ' ' Logical in Algoritmos' ' , according to COAST (2005), all algorithm presents basic characteristics that must be taken in consideration. An algorithm must leave of an initial point and always arrive at an end point; it does not have to be ambiguous, that is, to give edge to some interpretations; in some part of program, all its stages must be reached.
