Perhaps you should try some spelling variations:
"modified bayesian estimation algorithms" » "modified bayesian estimation algorithm", "modified bayesian optimization algorithms", "modified bayesian optimisation algorithm"
"modified adaptive quantization algorithmssss" » "modified adaptive ventilation algorithmssss", "modified passive quantization algorithmssss"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified bayesian estimation algorithms") or ("modified adaptive quantization algorithmssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian estimation algorithms") OR ("modified adaptive quantization algorithmssss")).
• Removing quotes may allow a broader search: (( modified bayesian estimation algorithms ) or ( modified adaptive quantization algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian estimation algorithms") or ("modified adaptive quantization algorithmssss"))*.
