Perhaps you should try some spelling variations:
"by computational in efficient programming" » "by computational in efficient processing" (Expand search), "by computational in fragment programming" (Expand search), "by computational in different programming" (Expand search), "_ computational in efficient programming" (Expand search), "and computational in efficient programming" (Expand search), "by computational and efficient programming" (Expand search), "by computational _ efficient programming" (Expand search), "by computational 3d efficient programming" (Expand search), "by computational an efficient programming" (Expand search), "by computational on efficient programming" (Expand search), "by computational is efficient programming" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python python python programming" (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: (("by computational in efficient programming") OR ("using python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"by computational in efficient programming\") OR (\"using python python python programming\"))*".
• Removing quotes may allow a broader search: (( by computational in efficient programming ) OR ( using python python python programming ))*.
