Perhaps you should try some spelling variations:
"coder computational algorithms complexity doi" » "coder computational algorithmic complexity doi" (Expand search), "code computational algorithms complexity doi" (Expand search), "poder computacional algorithms complexity doi" (Expand search), "model computational algorithms complexity doi" (Expand search), "coder computational algorithms complexity how" (Expand search), "coder computational algorithms complexity dc" (Expand search), "coder computational algorithms complexity dsp" (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 complexity doi\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder computational algorithms complexity doi ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder computational algorithms complexity doi") OR ("api python python python programming"))*.
