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 total python python programming" » "using total pythons python programming" (Expand search), "using total piton python programming" (Expand search), "using total pitons python programming" (Expand search), "using tool 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 total python python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation using linear programming ) OR ( using total python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation using linear programming") OR ("using total python python programming"))*.
