  • Some popular functions used to test global optimization algorithms have multiple local optima, all with the same value. That is all local optima are also global optima. This paper suggests that such functions are easily fortified by adding a localized bump at the location of one of the optima, making the functions more difficult to optimize due to the multiple competing local optima. This process is illustrated here for the Branin-Hoo function, which has three global optima. We use the popular… CONTINUE READING
