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

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