How it works
Changing mutation options for breeding
Breeding mutation is the amount of variation in the random selection of new
plant parameters from a normal (bell-shaped) distribution. The mean (average) of
the distribution is either the value from one parent or the blended value from
two parents. At 100% mutation the standard deviation of the normal distribution
is half of the mean. At 0% mutation there is no variation, and all offspring
have exactly the same value as the mean for each parameter.
To change mutation options,
Choose Custom from the breeder Variation menu.
Click the Mutations tab.
If you don't want to differentiate between parameter sections, just click on the mutation slider and drag to the left or right. All parameters will use the new mutation value. -or-
If you want to differentiate between parameter sections, click the Sections button. A list of parameter sections will appear (the same list as in the main window). For each section or sections you want to set the mutation for, select the sections in the list, then drag the mutation slider to the left or right. How this works with the breeder Variation menu:
When you choose Low breeding variation from the breeder Variation menu, the mutation percent for all parameter sections is set to 20%. At Medium variation the mutation percent is 60%. At High variation the mutation percent is 100%.
