Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"how graining methods algorithm" » "how learning methods algorithm", "how learning method algorithm", "how making methods algorithm", "new training methods algorithm", "goi training methods algorithm"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithm") OR ("how graining methods algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) or ( how graining methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithm") or ("how graining methods algorithm"))*.
