Perhaps you should try some spelling variations:
"advanced computations using linear programming" » "advanced computational using linear programming" (Expand search), "advance computational using linear programming" (Expand search), "advanced communications using linear programming" (Expand search), "advanced computation using linear programming" (Expand search), "advanced populations using linear programming" (Expand search), "advanced computations in linear programming" (Expand search)
"using code form python programming" » "using cone form python programming" (Expand search), "using co form python programming" (Expand search), "using co2 form 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: (("advanced computations using linear programming") OR ("using code form python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced computations using linear programming\") OR (\"using code form python programming\"))".
• Removing quotes may allow a broader search: (( advanced computations using linear programming ) OR ( using code form python programming )).
• Adding a wildcard symbol may retrieve word variants: (("advanced computations using linear programming") OR ("using code form python programming"))*.
