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"
"machinery using raw algorithm" » "machines using raw algorithm", "machinery using adam algorithm", "machinery using _ algorithm", "machinery using mom algorithm", "machinery using real algorithm", "machinery using a algorithm", "machinery using low 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 optimized algorithm") OR ("machinery using raw algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimized algorithm\") OR (\"machinery using raw algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimized algorithm ) OR ( machinery using raw algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimized algorithm") OR ("machinery using raw algorithm"))*.
