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