Figure 6

Example of reference Pareto-front P and Generational Distance ( GD ) metric. GD finds the average Euclidean distance from each i-th solution in Q to the nearest solution in P . The lower the GD value, the more effective are the architectures regarding self-adaptation quality attributes. The style-based architecture r is shown as more effective than those produced by the search-based approach. That is one of the null hypotheses investigated herein.
