Here is a basic code C++ to solve the XOR problem using ANN_MLP:

Here is the source code that performs the setLayerSizes function:

So it looks there is no set maximum number of layers, nor is there a maximum for each layer -- it's only what your RAM can handle.

So it looks there is no set maximum number of layers, nor is there a maximum number of neurons for each layer -- it's only what your RAM can handle.

Here is the source code that performs setTermCriteria:

It looks like the maximum number of training sessions is 1000:
