Perhaps you should try some spelling variations:
"and computational in complex program" » "_ computational in complex program" (Expand search), "and computational and complex program" (Expand search), "and computational _ complex program" (Expand search), "and computational 3d complex program" (Expand search), "and computational in simplex program" (Expand search), "and computational in complex programmes" (Expand search), "and computational in complex prograded" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ 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: (("and computational in complex program") OR ("using in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computational in complex program\") OR (\"using in python python programming\"))*".
• Removing quotes may allow a broader search: (( and computational in complex program ) OR ( using in python python programming ))*.
