This is Fig. 2 from the 2013 GENOPT paper2. Shown here are results from the specific case called “oneskirt”: Optimization of the long propellant tank with one skirt connected to the midlength of the cylindrical part of the propellant tank. (See Fig. 1 two slides hence.) The starting design at the beginning of the second execution of SUPEROPT (next figure) is the same as that labeled here, “Local optimum design no. 1”. WGT, TNKNRM and CONNRM are specified by the End user in the GENOPT processor called “BEGIN”.
