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 method algorithm" » "machinery using mom algorithm", "machines using method algorithm", "machinery nursing methods algorithm", "machinery focusing method algorithm", "machinery using metal 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: "((\"machinery using method algorithm\") OR (\"modified objective optimized algorithms\"))~".
• Removing quotes may allow a broader search: (( machinery using method algorithm ) OR ( modified objective optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("machinery using method algorithm") OR ("modified objective optimized algorithms"))*.
