Perhaps you should try some spelling variations:
"coder _ multiobjective algorithm array" » "coder _ objective algorithm array" (Expand search), "coder _ objective algorithms array" (Expand search), "coder _ multiobjective algoritmos array" (Expand search), "coder _ multiobjective algorithm aaa" (Expand search), "coder _ multiobjective algorithm binary" (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 _ multiobjective algorithm array\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder _ multiobjective algorithm array ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder _ multiobjective algorithm array") OR ("api python python python programming"))*.
