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