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