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