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: (("mobile learning emotion algorithm") OR ("modified objective optimized algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mobile learning emotion algorithm\") OR (\"modified objective optimized algorithm\"))".
• Removing quotes may allow a broader search: (( mobile learning emotion algorithm ) OR ( modified objective optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("mobile learning emotion algorithm") OR ("modified objective optimized algorithm"))*.
