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