Perhaps you should try some spelling variations:
"modified objective optimized algorithm" » "modified objective optimal algorithm", "modified objective optimization algorithm", "modified objective optimized algorithms", "modified objective optimizer algorithms"
"mobile learning emotion algorithm" » "mobile learning evolution algorithm", "mobile learning estimation algorithm", "mobile learning predation algorithm", "mobile learning method algorithm", "machine learning emotion 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 optimized algorithm") OR ("mobile learning emotion algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimized algorithm\") OR (\"mobile learning emotion algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimized algorithm ) OR ( mobile learning emotion algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimized algorithm") OR ("mobile learning emotion algorithm"))*.
