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