Perhaps you should try some spelling variations:
"coder and optimization algorithm parallelization" » "coder and optimization automatic parallelization" (Expand search), "code and optimization algorithm parallelization" (Expand search), "codes and optimization algorithm parallelization" (Expand search), "poder and optimization algorithm parallelization" (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 and optimization algorithm parallelization\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder and optimization algorithm parallelization ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder and optimization algorithm parallelization") OR ("api python python python programming"))*.
