>The earth should actually be a very easy function to optimize. Since the earth is primarily covered by oceans, more than two thirds of possible valid inputs for this function return the optimal cost function value. I guess if you're going to count the surface of the oceans as part of the descent you have to remember the surface of the ocean is not uniform in altitude neither due to tidal forces nor other factors.
