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 caging optimized algorithms" » "modified caging optimized algorithm", "modified caging optimizer algorithms", "modified caging optimization algorithms", "modified aging optimized algorithms", "modified changing optimized algorithms", "modified charging optimized algorithms"

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 adaptive quantization algorithms") OR ("modified caging optimized algorithms"))~.
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithms ) or ( modified caging optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive quantization algorithms") or ("modified caging optimized algorithms"))*.
