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