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