Perhaps you should try some spelling variations:
"coder computational algorithms open problems" » "code computational algorithms open problems" (Expand search), "poder computacional algorithms open problems" (Expand search), "model computational algorithms open problems" (Expand search), "coder computational algorithms openmp problems" (Expand search), "coder computational algorithms on problems" (Expand search), "coder computational algorithms over problems" (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)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder computational algorithms open problems\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder computational algorithms open problems ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder computational algorithms open problems") OR ("api python python python programming"))*.
