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