Perhaps you should try some spelling variations:
"based computation in complex problem" » "based computational in complex problem" (Expand search), "based competition in complex problem" (Expand search), "based compilation in complex problem" (Expand search), "based computation in complex problems" (Expand search), "based computation and complex problem" (Expand search), "based computation of complex problem" (Expand search), "based imputation in complex 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("based computation in complex problem") OR ("using python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computation in complex problem\") OR (\"using python python python programming\"))".
• Removing quotes may allow a broader search: (( based computation in complex problem ) OR ( using python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computation in complex problem") OR ("using python python python programming"))*.
