Perhaps you should try some spelling variations:
"case complexity based algorithm in" » "case complexity and algorithm in" (Expand search), "case complexity beyond algorithm in" (Expand search), "case complexity index algorithm in" (Expand search), "the complexity based algorithm in" (Expand search), "and complexity based algorithm in" (Expand search), "case complexity based algorithm and" (Expand search), "case complexity based algorithm _" (Expand search), "case complexity based algorithm with" (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: (("case complexity based algorithm in") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"case complexity based algorithm in\") OR (\"api python python python programming\"))".
• Removing quotes may allow a broader search: (( case complexity based algorithm in ) OR ( api python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("case complexity based algorithm in") OR ("api python python python programming"))*.
