Perhaps you should try some spelling variations:
"whose computation algorithms complexity from" » "whose computational algorithms complexity from" (Expand search), "whose computational algorithm complexity from" (Expand search), "whose calculation algorithms complexity from" (Expand search), "whose computation algorithmic complexity from" (Expand search), "pose computation algorithms complexity from" (Expand search), "these computations algorithms complexity from" (Expand search), "the computation algorithms complexity from" (Expand search)
"using using python python programming" » "using using pythons python programming" (Expand search), "using using piton python programming" (Expand search), "using using pitons python programming" (Expand search), "using usando python python programming" (Expand search), "using in python python programming" (Expand search), "using fusing python python programming" (Expand search), "housing using python python programming" (Expand search), "nursing using 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: (("whose computation algorithms complexity from") OR ("using using python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"whose computation algorithms complexity from\") OR (\"using using python python programming\"))".
• Removing quotes may allow a broader search: (( whose computation algorithms complexity from ) OR ( using using python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("whose computation algorithms complexity from") OR ("using using python python programming"))*.
