On directed Barabasi-Albert networks with two and seven neighbours selectedby each added site, the Ising model does not seem to show a spontaneousmagnetisation. Instead, the decay time for flipping of the magnetisationfollows an Arrhenius law for Metropolis and Glauber algorithms, but for Wolffcluster flipping the magnetisation decays exponentially with time. On thesenetworks the magnetisation behaviour of the Ising model, with Glauber,HeatBath,  Metropolis, Wolf or Swendsen-Wang algorithm competing against Kawasakidynamics, is studied by Monte Carlo simulations. We show that the modelexhibits the phenomenon of self-organisation (= stationary equilibrium) when  Kawasaki dynamics is not dominant in its competition with Glauber, HeatBathand Swendsen-Wang algorithms. Only for Wolff cluster flipping themagnetisation, this phenomenon occurs after an exponentially decay ofmagnetisation with time. The Metropolis results are independent of competition.We also study the same process of competition described above but with Kawasakidynamics at the same temperature as the other algorithms. The obtained resultsare similar for Wolff cluster flipping, Metropolis and Swendsen-Wang algorithmsbut different for HeatBath.Comment: 13 pages, including many figures, for Int. J. Mod. Phys.
