Perhaps you should try some spelling variations:
"advance computational using linear programming" » "advanced computational using linear programming" (Expand search), "advancing computational using linear programming" (Expand search), "advanced computations using linear programming" (Expand search), "advance computation using linear programming" (Expand search), "advance computations using linear programming" (Expand search), "advance computacional usinas 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: "((\"advance computational using linear programming\") OR (\"using total python python programming\"))~".
• Removing quotes may allow a broader search: (( advance computational using linear programming ) OR ( using total python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advance computational using linear programming") OR ("using total python python programming"))*.
