Perhaps you should try some spelling variations:
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation 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.

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