Perhaps you should try some spelling variations:
"advance computational using linear programming" » "advanced computational using linear programming" (Expand search), "advancing computational using linear programming" (Expand search), "advanced computations using linear programming" (Expand search), "advance computation using linear programming" (Expand search), "advance computations using linear programming" (Expand search), "advance computacional usinas linear programming" (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: (("advance computational using linear programming") OR ("using in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advance computational using linear programming\") OR (\"using in python python programming\"))".
• Removing quotes may allow a broader search: (( advance computational using linear programming ) OR ( using in python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("advance computational using linear programming") OR ("using in python python programming"))*.
