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