Perhaps you should try some spelling variations:
"modified objective optimizer algorithms" » "modified objective optimized algorithms", "modified objective optimized algorithm", "modified objective optimization algorithms", "modified objective optimal algorithms"
"mapping learning emotion algorithm" » "mapping learning evolution algorithm", "mapping learning estimation algorithm", "mapping learning predation algorithm", "machine learning emotion algorithm", "enabling learning emotion algorithm", "mapping learning method algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective optimizer algorithms") OR ("mapping learning emotion algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimizer algorithms\") OR (\"mapping learning emotion algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimizer algorithms ) OR ( mapping learning emotion algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimizer algorithms") OR ("mapping learning emotion algorithm"))*.
