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