Reversals and transpositions are the most common kind of genome rearrangements, which are operations that affect large fragments of genomes. With rearrangements is possible to establish the divergence between individuals along evolution. The minimum distance between two certain genomes is assumed as being the evolutionary distance between them and it can be calculated by using scenarios involving rearrangements. Therefore, a sorting problem of genomes by using one or more kinds of rearrangements is the problem of finding the minimum distance between two genomes by using the allowed rearrangements. When the rearrangement operations affect segments of the beginning or of the end of the genome, we say that they are prefix or suffix rearrangements, respectively. This proposal presents some initial concepts and results already existent about related problems, as well as specifies the goal of our thesis, which aims to deal with sorting problems by using reversal and transposition operations in their versions of suffix and prefix.
