Perhaps you should try some spelling variations:
"using computational time complexity from" » "and computational time complexity from" (Expand search), "using computational tool complexity from" (Expand search), "using computational code complexity from" (Expand search), "using computational tools complexity from" (Expand search), "using computational the complexity from" (Expand search), "using computational regime complexity from" (Expand search), "using computational case complexity from" (Expand search)
"using codigo python python programming" » "using codigo pythons python programming" (Expand search), "using codigo piton python programming" (Expand search), "using codigo pitons python programming" (Expand search), "using indigo python python programming" (Expand search), "using coding python python programming" (Expand search), "using codium 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: (("using computational time complexity from") OR ("using codigo python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational time complexity from\") OR (\"using codigo python python programming\"))".
• Removing quotes may allow a broader search: (( using computational time complexity from ) OR ( using codigo python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("using computational time complexity from") OR ("using codigo python python programming"))*.
