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