Goal Weighting

Specify a weighting for the combination of multiple goals.

This weighting is used to modify the contribution of the combination goals error to the global error during the fitness evaluation. The global error in each level of the tree is computed by taking the evaluated error of each goal, multiplying it by the indicated weighting factor, and then summing all of the resultant weighted errors in each branch-level of the tree.
Note: The weighting of each goal is shown in brackets in the model tree.
