Perhaps you should try some spelling variations:
"based computational in complexity from" » "and computational in complexity from" (Expand search), "by computational in complexity from" (Expand search), "based computational and complexity from" (Expand search), "based computational _ complexity from" (Expand search), "based computational 3d complexity from" (Expand search), "based computational on complexity from" (Expand search)
"using code from python programming" » "using code from pathogen programming" (Expand search), "using code from anthony programming" (Expand search), "using cone from python programming" (Expand search), "using co from python programming" (Expand search), "using co2 from python programming" (Expand search), "using code form python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational in complexity from\") OR (\"using code from python programming\"))~".
• Removing quotes may allow a broader search: (( based computational in complexity from ) OR ( using code from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational in complexity from") OR ("using code from python programming"))*.
