Perhaps you should try some spelling variations:
"active application python python programming" » "active replication python python programming" (Expand search), "activity application python python programming" (Expand search), "native applications python python programming" (Expand search), "active application method python programming" (Expand search), "active aplicativo python python programming" (Expand search), "active application methods python programming" (Expand search), "active application pythons python programming" (Expand search), "active application piton python programming" (Expand search), "active application pitons python programming" (Expand search)
"_ convolutional and learning problems" » "_ convolution and learning problems" (Expand search), "_ conventional and learning problems" (Expand search), "_ convolutional codes learning problems" (Expand search), "_ convolutional and learning process" (Expand search), "_ convolutional and learning projects" (Expand search), "_ convolutional and packing problems" (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 and learning problems\") OR (\"active application python python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional and learning problems ) OR ( active application python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional and learning problems") OR ("active application python python programming"))*.
