Perhaps you should try some spelling variations:
"science applications python python programming" » "science applications methods python programming" (Expand search), "science applications how python programming" (Expand search), "science aplicativo python python programming" (Expand search), "science applications pythons python programming" (Expand search), "science applications piton python programming" (Expand search), "science applications pitons python programming" (Expand search)
"_ convolutional codes coding program" » "_ convolutional codes cloning program" (Expand search), "_ convolutional codes loading program" (Expand search), "_ convolutional codes cooling programs" (Expand search), "_ convolutional codes going program" (Expand search), "_ convolutional modern coding program" (Expand search), "_ convolutional clouds coding 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: "((\"_ convolutional codes coding program\") OR (\"science applications python python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional codes coding program ) OR ( science applications python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional codes coding program") OR ("science applications python python programming"))*.
