Maximizing the Pearson's correlation coefficient r² is equivalent to maximization of the scaled MSE, however the calculation of r² is more efficient because it can be calculated in a single pass while the scaled MSE has to be calculated in two passes.

r4190:

  • Moved upper and lower estimation limit parameters into ISymbolicRegressionEvaluator interface and introduced an Evaluate method in the interface in preparation for a ISymbolicRegressionEvaluator parameter for the validation best solution analyzer.
