Hierarchical importance sampling instead of annealing

GECCO 2011 is going to be held in Ireland. I'm going to attend the conference and introduce my research results in a poster session. The research result is about "importance sampling regularization for estimation of distribution algorithms".

I have uploaded a short note about statistical evolutionary algorithms. In evolutionary algorithms, the Boltzmann distribution is important. However, its parameter, the inverse temperature, is difficult to control. My doctor thesis shows a method to overcome this difficulty. The note provides calculation details, that is, free energy and moment generation, which are well known in statistical physics.
