Perhaps you should try some spelling variations:
"advanced computational using linear programming" » "and computational using linear programming" (Expand search), "based computational using linear programming" (Expand search), "advanced computation using linear programming" (Expand search), "advanced computations using linear programming" (Expand search), "advanced computacional usinas linear programming" (Expand search)
"using long python python programming" » "using long pythons python programming" (Expand search), "using long piton python programming" (Expand search), "using long pitons python programming" (Expand search), "using on python python programming" (Expand search), "using monty python python programming" (Expand search), "using using python python programming" (Expand search), "during long python python programming" (Expand search), "using low 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 computational using linear programming\") OR (\"using long python python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computational using linear programming ) OR ( using long python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computational using linear programming") OR ("using long python python programming"))*.
