Perhaps you should try some spelling variations:
"using computational in practical problems" » "and computational in practical problems" (Expand search), "using computational in operational problems" (Expand search), "using computational and practical problems" (Expand search), "using computational _ practical problems" (Expand search), "using computational 3d practical problems" (Expand search), "using computational in practice 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: "((\"using computational in practical problems\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( using computational in practical problems ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational in practical problems") OR ("using python python python programming"))*.
