Perhaps you should try some spelling variations:
"_ computation using linear programming" » "_ computations using linear programming" (Expand search), "_ computation in linear programming" (Expand search), "_ composition using 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: "((\"_ computation using linear programming\") OR (\"using code from python programming\"))~".
• Removing quotes may allow a broader search: (( _ computation using linear programming ) OR ( using code from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ computation using linear programming") OR ("using code from python programming"))*.
