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 location optimization algorithm" » "modified location optimization algorithms", "modified location optimisation algorithm", "modified location estimation algorithm", "modified allocation optimization algorithm", "modified static optimization algorithm", "modified carbon optimization 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 adaptive quantization algorithms") OR ("modified location optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithms ) or ( modified location optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive quantization algorithms") or ("modified location optimization algorithm"))*.
