Perhaps you should try some spelling variations:
"code complexity data computational cost" » "code complexity and computational cost" (Expand search), "code complexity via computational cost" (Expand search), "code complexity based computational cost" (Expand search), "code complexity data computational and" (Expand search), "code complexity data computational design" (Expand search), "code complexity data computational vision" (Expand search), "case complexity data computational cost" (Expand search), "care complexity data computational cost" (Expand search), "the complexity data computational cost" (Expand search), "code complexity at computational cost" (Expand search), "code complexity an computational cost" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking 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: (("code complexity data computational cost") OR ("using coding python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"code complexity data computational cost\") OR (\"using coding python python programming\"))*".
• Removing quotes may allow a broader search: (( code complexity data computational cost ) OR ( using coding python python programming ))*.
