Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"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: (("machines using method algorithm") or ("modified multiobjective optimizer algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines using method algorithm") OR ("modified multiobjective optimizer algorithms"))*.
• Removing quotes may allow a broader search: (( machines using method algorithm ) or ( modified multiobjective optimizer algorithms ))*.
