Perhaps you should try some spelling variations:
"modified objective evolutionary algorithm" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified learning method algorithm\") OR (\"modified objective evolutionary algorithm\"))~".
• Removing quotes may allow a broader search: (( modified learning method algorithm ) OR ( modified objective evolutionary algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning method algorithm") OR ("modified objective evolutionary algorithm"))*.
