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 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.

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