This section provides an Excel/VBA program, r3eda Generic LF Det or Stoch Function Optimizer Styblinsky-Tang 2017-04-23, and user instructions, r3eda-site-generic-lf-det-or-stoch-function-optimizer-user-guide-2016-09-30, for Leapfrogging optimization of a function of up to 20 Decision Variables. The function can be either deterministic or stochastic. Although I programmed a popular Styblinsky-Tang function as the function to be optimized, you can easily edit the program to include your own function. Although the display and algorithm is limited to 20 DVs, you could edit the file to increase this number.
