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