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