Search for a minimum of sphere function of 15 variables F(X1,X2,...,X15) = X1^2 + X2^2 + ... + X15^2 from the starting point with coordinates X1 = X2 = ... = X15 = 10. The search is unconstrained. The function has a minimum at zero values of all coordinates. See details at http://www.chem-astu.ru/science/opt/eindex.shtml # Code of the optimized function: {1}*{1} + {2}*{2} + {3}*{3} + {4}*{4} + {5}*{5} + {6}*{6} + {7}*{7} + {8}*{8} + {9}*{9} + {10}*{10} + {11}*{11} + {12}*{12} + {13}*{13} + {14}*{14} + {15}*{15} # Type of the optimization (1 - search for a maximum, -1 - search for a minimum): -1 # Boundaries (on left and right) and starting point coordinates (middle) separated by comma. If a boundary is absent, a comma MUST BE PRESENT. , 10, , 10, , 10, , 10, , 10, , 10, , 10, , 10, , 10, , 10, , 10, , 10, , 10, , 10, , 10,
