Perhaps you should try some spelling variations:
"modified bayesian optimization algorithmss" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "modified bayesian estimation algorithm", "modified bayesian optimisation algorithms", "modified bayesian estimation algorithmss"
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation 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 parameters optimization algorithms") or ("modified bayesian optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimization algorithms") OR ("modified bayesian optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified parameters optimization algorithms ) or ( modified bayesian optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithms") or ("modified bayesian optimization algorithmss"))*.
