Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer 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: "((\"modified multiobjective optimized algorithms\") OR (\"machinery using method algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) OR ( machinery using method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithms") OR ("machinery using method algorithm"))*.
