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