How can I find the optimal value of two separate outputs with similar inputs in the neural network toolbox?

hello,

I have a "Data" matrix where the first two columns are for inputs and the second two are for outputs. A separate neural network was used for each output, and as a result, the maximum state was obtained for each separately. How can I find the best outputs simultaneously with same inputs and show which inputs are more appropriate?

There are 2 workspaces in the attachment, which include 2 neural network outputs "YtotNet".

thank you
