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