Perhaps you should try some spelling variations:
"code complexity using subsampling errors" » "code complexity using sampling errors" (Expand search), "code complexity using nonsampling errors" (Expand search), "code complexity using sampling error" (Expand search), "code complexity and subsampling errors" (Expand search), "code complexity during subsampling errors" (Expand search), "code complexity un subsampling errors" (Expand search), "code complexity user subsampling errors" (Expand search), "case complexity using subsampling errors" (Expand search), "care complexity using subsampling errors" (Expand search), "the complexity using subsampling errors" (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 using subsampling errors") OR ("using coding python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"code complexity using subsampling errors\") OR (\"using coding python python programming\"))*".
• Removing quotes may allow a broader search: (( code complexity using subsampling errors ) OR ( using coding python python programming ))*.
