Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"machinery using force algorithm" » "machines using force algorithm", "machinery using source algorithm", "machinery using search algorithm", "machinery using morse algorithm", "machinery cutting force 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 algorithm") or ("machinery using force algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithm") OR ("machinery using force algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) or ( machinery using force algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithm") or ("machinery using force algorithm"))*.
