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