  abstract     = {This chapter deals with the application of P systems
                  to sorting problems. Traditional studies of sorting assume
                  constant time for comparing two numbers and compute
                  the time complexity with respect to the number of components
                  of a vector to be sorted. Here, we assume the number of components
                  to be a fixed number k, and study various algorithms
                  based on different models of P systems and their time complexities
                  with respect to the maximal number or to the sum of the numbers.
                  Massively parallel computations that can be realized
                  within the framework of P systems may lead to major improvements
                  in solving the classical integer sorting problems.
                  Despite this important characteristic, we will see that
                  depending on the model used, the massive parallelism feature
                  cannot be always used, and so some results will have complexities
                  ``comparable'' with the classical integer sorting algorithms.
                  Still, computing a word (ordered) from a multiset (unordered)
                  can be a goal not only for computer science, but also, e.g.
                  for biosynthesis (separating mixed objects according
                  to some characteristics). Here, we will move from
                  ranking algorithms that, starting with numbers
                  represented as multisets, produce symbols in an order
                  to effective sorting algorithms.},
