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