Advanced Parameters (Multi Result Optimization)

Optimization menu > Multi Result > Settings > Edit

Note
Only available if the Advanced Settings are enabled. Changes should be made only by experienced users.

The Advanced Parameters window for multi result optimization contains the following elements:

Initial Population Size

Size of the initial population – should be approximately 4 times the value of the number of children-generating parents (Parent Population Size).

Start Design

The following options are available for selecting the start values:

Space Filling	The start values are selected space-filling by the Sobol algorithm.
All Edges	Start values = all corners of the experimental space (2^{Number of parameters}). The rest of the population is distributed in the parameter space according to the Sobol algorithm.

Parent Population Size (mu)

Number of parents generating children (for the first as well as for all other populations).

Child Population Size (lambda > mu)

Number of the children generated by the parents in each case – should be approximately 4 times the number of children-generating parents ("Parent Population Size").

Archive Size

The maximum number of pareto-optimal solutions across all generations – should be approximately 4 times the number of children-generating parents ("Parent Population Size").

More precisely: Size of the archive in which the best pareto-optimal solutions are placed in each case. The parents are taken from this archive and the children generated from them (depending on whether they feature a better or worse solution than the ones already stored) are stored in the archive again.

Crossover [0..1]

Probability of the mixture of parents (recombination); should be set to 0.2.
