Perhaps you should try some spelling variations:
"using computational in clustering problem" » "and computational in clustering problem" (Expand search), "using computational in covering problem" (Expand search), "using computational and clustering problem" (Expand search), "using computational _ clustering problem" (Expand search), "using computational 3d clustering problem" (Expand search), "using computational on clustering problem" (Expand search), "using computational spin clustering problem" (Expand search)
"using code from python programming" » "using code from pathogen programming" (Expand search), "using code from anthony programming" (Expand search), "using cone from python programming" (Expand search), "using co from python programming" (Expand search), "using co2 from python programming" (Expand search), "using code form 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: (("using computational in clustering problem") OR ("using code from python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational in clustering problem\") OR (\"using code from python programming\"))".
• Removing quotes may allow a broader search: (( using computational in clustering problem ) OR ( using code from python programming )).
• Adding a wildcard symbol may retrieve word variants: (("using computational in clustering problem") OR ("using code from python programming"))*.
