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

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

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