Perhaps you should try some spelling variations:
"based computational using xml problem" » "and computational using xml problem" (Expand search), "by computational using xml problem" (Expand search), "based computation using xml problem" (Expand search), "based computations using xml problem" (Expand search), "based computacional usinas xml problem" (Expand search), "based computational using pbl problem" (Expand search), "based computational using hall problem" (Expand search), "based computational using real problem" (Expand search), "based computational using x problem" (Expand search), "based computational using xrd problem" (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 computational using xml problem\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational using xml problem ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational using xml problem") OR ("using python python python programming"))*.
