Perhaps you should try some spelling variations:
"based computational using integer programming" » "and computational using integer programming" (Expand search), "by computational using integer programming" (Expand search), "based computation using integer programming" (Expand search), "based computations using integer programming" (Expand search), "based computacional usinas integer programming" (Expand search), "based computational using linear programming" (Expand search), "based computational using inter programming" (Expand search), "based computational using internet programming" (Expand search), "based computational using integral programming" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python python 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: (("based computational using integer programming") OR ("using python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational using integer programming\") OR (\"using python python python programming\"))*".
• Removing quotes may allow a broader search: (( based computational using integer programming ) OR ( using python python python programming ))*.
