Perhaps you should try some spelling variations:
"using computational complexity coverage in" » "and computational complexity coverage in" (Expand search), "using computational complete coverage in" (Expand search), "using computational complexity convergence in" (Expand search), "using computational complexity coverage of" (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: "((\"using computational complexity coverage in\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( using computational complexity coverage in ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational complexity coverage in") OR ("using codigo python python programming"))*.
