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