Returns true if min/max/def was really available (otherwise it is just invented). 187 static bool mutateRandomNeuronOrNeuroclassProperty(Neuro* n); ///<high-level neuron mutation function, will select and mutate a random property of a neuron or its neuroclass. Returns true if successful and some property was actually mutated. Could return false when the neuron and its neuroclass have no properties, or when a randomly selected property was not suitable for mutation (for example a string or another non-number type). 187 188 static int selectRandomNeuronProperty(Neuro* n); ///<selects random property (either 0-based extraproperty of Neuro or NEUROCLASS_PROP_OFFSET-based property of its NeuroClass). -1 if Neuro has no properties. 188 189 static double mutateNeuronProperty(double current, Neuro *n, int propindex); ///<returns value \e current mutated for the property \e propindex of NeuroClass \e nc or for extraproperty (\e propindex - NEUROCLASS_PROP_OFFSET) of Neuro. Neuro is used as read-only. Give \e propindex == -1 to mutate connection weight (\e nc is then ignored).
