If something goes wrong, you may want to continue the calculation from the point where it stopped — or from an earlier point. If all you want to do is continue the run from where it stopped, you do not need to change any settings.
If you want to restart from a particular generation in a particular results-folder, then specify pickUpGen = number of the generation from which you want to start, pickUpFolder = number of results-folder (e.g., 1 for results1, 2 for results2, …) from which the restart needs to be. If pickUpGen=0, then a new calculation is started. The default values for both parameters are 0. For example, to restart a calculation performed in the folder results5 from generation number 10, specify:
10 : pickUpGen
5 : pickUpFolder
