Perhaps you should try some spelling variations:
"modified objective optimized algorithms" » "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimization algorithms", "modified objective optimal algorithms"
"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.

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