Investigation of Examples of E-Education Environment for Scientific Collaboration and Distance Graduate Studies, Part 1

Jonas Mockus
2006 Informatica  
Thus we need some automatic procedures for tuning the heuristics. That helps comparing results of different heuristics. This enhance their efficiency, too.  ...  In this paper the theory and applications of Bayesian Heuristic Approach are discussed. In the next paper examples of Bayesian Approach to automated tuning of heuristics will be regarded.  ...  A convenient theoretical concept is the Bayesian approach. We apply this approach for automatic tuning of heuristic parameters and for search of optimal mixtures of heuristics.  ...
