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