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: (("how graining methods algorithm") OR ("modified multiobjective optimized algorithm"))~.
• Removing quotes may allow a broader search: (( how graining methods algorithm ) or ( modified multiobjective optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("how graining methods algorithm") or ("modified multiobjective optimized algorithm"))*.
