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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified passive quantization algorithmssss\") OR (\"modified bayesian optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified passive quantization algorithmssss ) OR ( modified bayesian optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified passive quantization algorithmssss") OR ("modified bayesian optimization algorithms"))*.
