Perhaps you should try some spelling variations:
"and computational of complexity from" » "_ computational of complexity from" (Expand search), "and computational one complexity from" (Expand search), "and computational _ complexity from" (Expand search), "and computational 3d 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.

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