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

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