EXAMPLES OF EQUATION BASED OPTIMIZATION
AnXplorer can perform general equation based function optimi-
zation as well. It is especially suitable for any cost function which
is known to have multiple local and global minima. A few exam-
ples of well known benchmark functions for optimization algo-
rithms are shown next.
Rastriginâs function
A visualization of Rastriginâs function for 2 variables is shown in
ï¬gure 6. The function is highly multimodal with numerous local
optima. The global optima lies at the point where all variables
have the value 0. AnXplorer has been used to ï¬nd the global op-
tima of this function for many (â¥8) variables.
Griewankâs function
Another example of a multimodal function with numerous local
optima is the Griewankâs function. The visualization for 2 vari-
ables is shown in ï¬gure 7. Here, too, the global minimum lies at
the point where all variables are 0. AnXplorer successfully ï¬nds
this point for several variables.
