Perhaps you should try some spelling variations:
"activity allocation python python programming" » "activity application python python programming" (Expand search), "activity association python python programming" (Expand search), "activity alteration python python programming" (Expand search), "activity allocation method python programming" (Expand search), "activity allocation methods python programming" (Expand search), "activity allocation pattern python programming" (Expand search), "activity allocation pythons python programming" (Expand search), "activity allocation piton python programming" (Expand search), "activity allocation pitons python programming" (Expand search)
"_ convolutional code learning process" » "_ convolutional codes learning process" (Expand search), "_ convolutional and learning process" (Expand search), "_ convolucional cnn learning process" (Expand search), "_ convolutional care learning process" (Expand search), "_ convolutional home learning process" (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: "((\"_ convolutional code learning process\") OR (\"activity allocation python python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional code learning process ) OR ( activity allocation python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional code learning process") OR ("activity allocation python python programming"))*.
