ALPS evaluation in financial portfolio optimisation
— Hornby’s Age-Layered Population Structure claims to reduce premature convergence in Evolutionary Algorithms. We provide the first evaluation of ALPS on a realworld problem ...

Heuristic search for non-linear cryptanalytic approximations
— In this work, we show that heuristic techniques (particularly Simulated Annealing) can be successfully applied in the search of good non-linear approximations of cryptographic ...
