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

Try widening your search to All Fields.

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

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