Perhaps you should try some spelling variations:
"surface modifications in python programming" » "surface modification in python programming" (Expand search), "surface modification of python programming" (Expand search), "surface modifications _ python programming" (Expand search)
"deep convolutional code feeding program" » "deep convolutional codes feeding program" (Expand search), "deep convolutional and feeding program" (Expand search), "deep convolucional cnn feeding program" (Expand search), "deep convolutional chose feeding program" (Expand search), "deep convolutional care feeding program" (Expand search), "deep convolutional choice feeding program" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"deep convolutional code feeding program\") OR (\"surface modifications in python programming\"))~".
• Removing quotes may allow a broader search: (( deep convolutional code feeding program ) OR ( surface modifications in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("deep convolutional code feeding program") OR ("surface modifications in python programming"))*.
