Perhaps you should try some spelling variations:
"modified objective predation algorithm" » "modified objective allocation algorithm", "modified objective predators algorithm", "modified objective estimation algorithm"
"machinery learning method algorithm" » "machine learning method algorithm", "machinery learning mom algorithm", "machinery learning methods algorithm", "machinery graining methods algorithm", "machinery 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: (("machinery learning method algorithm") OR ("modified objective predation algorithm"))~.
• Removing quotes may allow a broader search: (( machinery learning method algorithm ) or ( modified objective predation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("machinery learning method algorithm") or ("modified objective predation algorithm"))*.
