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 method algorithm" » "machines using mom algorithm", "machinery using method algorithm", "machines nursing methods algorithm", "machines focusing method algorithm", "machines using metal 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 method algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithms") OR ("machines using method algorithm"))*.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) or ( machines using method algorithm ))*.
