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 solution algorithm" » "mobile learning evolution algorithm", "mobile learning convolution algorithms", "mobile learning evolutionary algorithm", "mobile learning convolution algorithm", "mobile learning emotion algorithm", "machine learning solution algorithm"

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: "((\"modified objective optimized algorithms\") OR (\"mobile learning solution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective optimized algorithms ) OR ( mobile learning solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimized algorithms") OR ("mobile learning solution algorithm"))*.
