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