Perhaps you should try some spelling variations:
"modified bayesian optimization algorithmsss" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "modified bayesian optimisation algorithmss", "modified bayesian estimation algorithmsss", "modified bayesian estimation algorithmss"
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameters optimization algorithms"

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 bayesian optimization algorithmsss") or ("modified parameter optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimization algorithmsss") OR ("modified parameter optimization algorithms")).
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithmsss ) or ( modified parameter optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimization algorithmsss") or ("modified parameter optimization algorithms"))*.
