Perhaps you should try some spelling variations:
"modified objective optimized algorithm" » "modified objective optimal algorithm", "modified objective optimization algorithm", "modified objective optimized algorithms", "modified objective optimizer algorithms"
"machines learning method algorithm" » "machine learning method algorithm", "active learning method algorithm", "mapping learning method algorithm", "machines learning mom algorithm", "machines learning methods algorithm", "machines graining methods algorithm", "machines 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: (("machines learning method algorithm") OR ("modified objective optimized algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machines learning method algorithm\") OR (\"modified objective optimized algorithm\"))*".
• Removing quotes may allow a broader search: (( machines learning method algorithm ) OR ( modified objective optimized algorithm ))*.
