Perhaps you should try some spelling variations:
"based computational using green programming" » "and computational using green programming" (Expand search), "by computational using green programming" (Expand search), "based computation using green programming" (Expand search), "based computations using green programming" (Expand search), "based computacional usinas green programming" (Expand search), "based computational using free programming" (Expand search), "based computational using driven programming" (Expand search), "based computational using element 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: (("based computational using green programming") OR ("using python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational using green programming\") OR (\"using python python python programming\"))*".
• Removing quotes may allow a broader search: (( based computational using green programming ) OR ( using python python python programming ))*.
