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