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