This function is used to access one of 50 objective functions that may be useful for benchmarking performance of global optimization algorithms.

1 |

`par` |
Vector of reals representing the parameter vector at which to evaluate the objective function. |

`fnName` |
A character vector representing the name of the objective function to use. Options are elements of c("Ackleys", "AluffiPentini", "BeckerLago", "Bohachevsky1", "Bohachevsky2", "Branin", "Camel3", "Camel6", "CosMix2", "CosMix4", "DekkersAarts", "Easom", "EMichalewicz", "Expo", "GoldPrice", "Griewank", "Gulf", "Hartman3", "Hartman6", "Hosaki", "Kowalik", "LM1", "LM2n10", "LM2n5", "McCormic", "MeyerRoth", "MieleCantrell", "Modlangerman", "ModRosenbrock", "MultiGauss", "Neumaier2", "Neumaier3", "Paviani", "Periodic", "PowellQ", "PriceTransistor", "Rastrigin", "Rosenbrock", "Salomon", "Schaffer1", "Schaffer2", "Schubert", "Schwefel", "Shekel10", "Shekel5", "Shekel7", "Shekelfox5", "Wood", "Zeldasine10", "Zeldasine20"). Unique partial matches to these elements are accepted. |

`checkDim` |
A boolean value that is |

Note that the factor of 0.02 in Ackley's function has been changed to the value commonly found in the literature, 0.2. Also, Storn's Tchebychev Problem in 9 and 17 dimensions was not included, since the global minima of the imlementation of these functions does not correspond to the global minima reported in the above paper.
