       abstract = "The Griewank test function for global unconstrained optimization has multiple local
         minima clustered around the global minimum at the origin. A new version of this test function is
         proposed that has a similar structure, but whose behavior at the local minima and maxima is
         non-smooth. This piecewise smooth version of the Griewank function represents an abs-factorable test
         case of objective functions for global non-smooth optimization as, for example, observed in the
         training of neural networks.",
