Description Usage Arguments Value
This method takes a user specified fitness function and runs the nsga2 algorithm on an ensemble using the nsga2 implementation provided in the mco package, in an attempt to locate parameters that achieve a desired response (determined by the fitness function). The method outputs a list describing the values for each simulation output measure, (or objective, res), an evolved set of parameter inputs (par), and a boolean stating whether the candidate is pareto optimal (pareto.optimal)
1 2 | emulator_parameter_evolution(function_to_evaluate,
nsga2_user_set_parameters, nsga2_settings)
|
function_to_evaluate |
A user-defined function that NSGA2 seeks to minimise |
nsga2_user_set_parameters |
An object containing the emulator input and output names, the input parameters for function to evaluate, minimum and maximum values for emulator inputs. These should be set using the function that creates that object prior to running this method |
nsga2_settings |
An object containing the population size, number of generations, crossover probability and mutation probability to be assessed. Again see the function nsga2_settings to set these values before running this function |
List containing evolved parameter sets, the output for the ensemble using those sets, and whether these sets are pareto optimal
