Perhaps you should try some spelling variations:
"based regression using integer programming" » "based regression using linear programming" (Expand search), "boosted regression using integer programming" (Expand search), "and regression using integer programming" (Expand search), "fixed regression using integer programming" (Expand search), "based regression testing integer programming" (Expand search), "based regression in integer programming" (Expand search), "based expression using integer programming" (Expand search), "based regression using inter programming" (Expand search), "based regression using internet programming" (Expand search), "based regression 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based regression using integer programming\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( based regression using integer programming ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based regression using integer programming") OR ("using python python python programming"))*.
