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