Perhaps you should try some spelling variations:
"based applications in python programming" » "and applications in python programming" (Expand search), "food applications in python programming" (Expand search), "based applications _ python programming" (Expand search)
"3d convolutional code changing program" » "3d convolutional codes changing program" (Expand search), "3d convolutional and changing program" (Expand search), "3d convolucional cnn changing program" (Expand search), "and convolutional code changing program" (Expand search), "of convolutional code changing program" (Expand search), "_ convolutional code changing program" (Expand search), "3d convolutional code change program" (Expand search), "3d convolutional code planning program" (Expand search), "3d convolutional code aging program" (Expand search), "3d convolutional model changing program" (Expand search), "3d convolutional cover changing program" (Expand search), "3d convolutional course changing program" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("3d convolutional code changing program") OR ("based applications in python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"3d convolutional code changing program\") OR (\"based applications in python programming\"))".
• Removing quotes may allow a broader search: (( 3d convolutional code changing program ) OR ( based applications in python programming )).
• Adding a wildcard symbol may retrieve word variants: (("3d convolutional code changing program") OR ("based applications in python programming"))*.
