Double_t	fConvCrit	improvements bigger than fConvCrit are counted as "improvement"
Int_t	fCycles	number of (nearly) independent calculation cycles
Int_t	fNsteps	convergence criteria: if no improvements > fConvCrit was achieved within the last fNsteps: cycle has "converged"
Int_t	fPopSize	number of individuals to start with
Double_t	fSC_factor	... with fSC_factor; if there were less improvements: divide by that factor; if there were exactly fSC_rate improvements, dont change anything
Int_t	fSC_rate	... fSC_rate improvements, than multiply the sigma of the gaussion which defines how the random numbers are generated ...
Int_t	fSC_steps	regulates how strong the mutations for the coordinates are: if within fSC_steps there were more than...
Int_t	fSaveBestFromCycle	store the best individuals from one cycle (these are included as "hints" in the last cycle of GA calculation)
Int_t	fSaveBestFromGeneration	store the best individuals from one generation (these are included as "hints" in the last cycle of GA calculation)
UInt_t	fSeed	Seed for the random generator (0 takes random seeds)
Bool_t	fTrim	take care, that the number of individuals is less fPopSize (trimming is done after the fitness of the individuals is assessed)
