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