Estimation of Distribution Algorithm (EDA)
Projects
at Essex
Estimation of Distribution Algorithms for
optimisation problems maintain a probability model at each generation, new trial
solutions are sampled from this model. The probability model is updated based on
statistical information extracted from these trail solutions.
Some other heuristics also use probability
model for guiding the search, for details, please visit
the homepage of
probability model based heuristics.
