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 from python programming" » "using code from pathogen programming" (Expand search), "using code from anthony programming" (Expand search), "using cone from python programming" (Expand search), "using co from python programming" (Expand search), "using co2 from python programming" (Expand search), "using code form python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced computations using linear programming\") OR (\"using code from python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computations using linear programming ) OR ( using code from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computations using linear programming") OR ("using code from python programming"))*.
