Perhaps you should try some spelling variations:
"code complexity exchange algorithm based" » "code complete exchange algorithm based" (Expand search), "code complexity channel algorithm based" (Expand search), "code commodity exchange algorithm based" (Expand search), "case complexity exchange algorithm based" (Expand search), "care complexity exchange algorithm based" (Expand search), "the complexity exchange algorithm based" (Expand search), "code complexity exchange algorithm and" (Expand search)
"api python python python programming" » "api pythons python python programming" (Expand search), "api piton python python programming" (Expand search), "api pitons python python programming" (Expand search), "rpa python python python programming" (Expand search), "manim python 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 exchange algorithm based") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"code complexity exchange algorithm based\") OR (\"api python python python programming\"))".
• Removing quotes may allow a broader search: (( code complexity exchange algorithm based ) OR ( api python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("code complexity exchange algorithm based") OR ("api python python python programming"))*.
