Perhaps you should try some spelling variations:
"machines learning method algorithm" » "machine learning method algorithm", "active learning method algorithm", "mapping learning method algorithm", "machines learning mom algorithm", "machines learning methods algorithm", "machines graining methods algorithm", "machines learning emotion algorithm"
"modified objective optimal algorithm" » "modified objective optimized algorithm", "modified objective optimized algorithms", "modified objective optimizer algorithms"

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: (("machines learning method algorithm") OR ("modified objective optimal algorithm"))~.
• Removing quotes may allow a broader search: (( machines learning method algorithm ) or ( modified objective optimal algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("machines learning method algorithm") or ("modified objective optimal algorithm"))*.
