Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"active graining methods algorithm" » "active learning methods algorithm", "active learning method algorithm", "active making 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 algorithms") OR ("active graining methods algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) or ( active graining methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithms") or ("active graining methods algorithm"))*.
