Perhaps you should try some spelling variations:
"code to estimation algorithm application" » "code to estimation algorithm optimization" (Expand search), "code to estimation algorithm selection" (Expand search), "code to estimation algorithms application" (Expand search), "code to optimization algorithm application" (Expand search), "code to optimization algorithms application" (Expand search), "code _ estimation algorithm application" (Expand search), "code an estimation algorithm application" (Expand search), "code to estimating algorithm application" (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 to estimation algorithm application") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"code to estimation algorithm application\") OR (\"api python python python programming\"))".
• Removing quotes may allow a broader search: (( code to estimation algorithm application ) OR ( api python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("code to estimation algorithm application") OR ("api python python python programming"))*.
