Perhaps you should try some spelling variations:
"coder approximation algorithm based program" » "coder approximation algorithms based program" (Expand search), "power approximation algorithm based program" (Expand search), "order approximation algorithm based program" (Expand search), "model approximation algorithm based program" (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 approximation algorithm based program\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder approximation algorithm based program ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder approximation algorithm based program") OR ("api python python python programming"))*.
