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