Perhaps you should try some spelling variations:
"_ computations in complex programming" » "_ computations in computer programming" (Expand search), "_ computations in convex programming" (Expand search), "_ computations in cortex programming" (Expand search), "_ computation in complex programming" (Expand search), "_ computation of complex programming" (Expand search), "_ computation and complex programming" (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: (("_ computations in complex programming") OR ("using python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ computations in complex programming\") OR (\"using python python python programming\"))".
• Removing quotes may allow a broader search: (( _ computations in complex programming ) OR ( using python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("_ computations in complex programming") OR ("using python python python programming"))*.
