Double_tfConvCritimprovements bigger than fConvCrit are counted as "improvement"
Int_tfCyclesnumber of (nearly) independent calculation cycles
Int_tfNstepsconvergence criteria: if no improvements > fConvCrit was achieved within the last fNsteps: cycle has "converged"
Int_tfPopSizenumber of individuals to start with
Double_tfSC_factor... with fSC_factor; if there were less improvements: divide by that factor; if there were exactly fSC_rate improvements, dont change anything
Int_tfSC_rate... fSC_rate improvements, than multiply the sigma of the gaussion which defines how the random numbers are generated ...
Int_tfSC_stepsregulates how strong the mutations for the coordinates are: if within fSC_steps there were more than...
Int_tfSaveBestFromCyclestore the best individuals from one cycle (these are included as "hints" in the last cycle of GA calculation)
Int_tfSaveBestFromGenerationstore the best individuals from one generation (these are included as "hints" in the last cycle of GA calculation)
UInt_tfSeedSeed for the random generator (0 takes random seeds)
Bool_tfTrimtake care, that the number of individuals is less fPopSize (trimming is done after the fitness of the individuals is assessed)
