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"
"modified graining methods algorithm" » "modified caging methods algorithm", "modified learning methods algorithm", "modified learning method algorithm", "modified making methods 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: (("modified graining methods algorithm") OR ("modified adaptive quantization algorithms"))~.
• Removing quotes may allow a broader search: (( modified graining methods algorithm ) or ( modified adaptive quantization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified graining methods algorithm") or ("modified adaptive quantization algorithms"))*.
