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 _ python python programming" » "using _ pythons python programming" (Expand search), "using _ piton python programming" (Expand search), "using _ pitons python programming" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("advanced computation using linear programming") OR ("using _ python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced computation using linear programming\") OR (\"using _ python python programming\"))".
• Removing quotes may allow a broader search: (( advanced computation using linear programming ) OR ( using _ python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("advanced computation using linear programming") OR ("using _ python python programming"))*.
