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