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