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