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

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 algorithms") or ("modified parameters estimation algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimization algorithms") OR ("modified parameters estimation algorithmss"))*.
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithms ) or ( modified parameters estimation algorithmss ))*.
