Perhaps you should try some spelling variations:
"modified bayesian optimisation algorithms" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "modified bayesian estimation algorithm", "modified bayesian optimization algorithms"
"modified passive optimization algorithms" » "modified passive optimisation algorithm", "modified passive estimation algorithms", "modified passive estimation algorithm", "modified bayesian optimization algorithms", "modified game optimization algorithms", "modified policy optimization algorithms", "modified adaptive optimization algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified passive optimization algorithms") OR ("modified bayesian optimisation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified passive optimization algorithms\") OR (\"modified bayesian optimisation algorithms\"))".
• Removing quotes may allow a broader search: (( modified passive optimization algorithms ) OR ( modified bayesian optimisation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified passive optimization algorithms") OR ("modified bayesian optimisation algorithms"))*.
