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

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 bayesian optimisation algorithms") or ("modified passive optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimisation algorithms") OR ("modified passive optimization algorithms")).
• Removing quotes may allow a broader search: (( modified bayesian optimisation algorithms ) or ( modified passive optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimisation algorithms") or ("modified passive optimization algorithms"))*.
