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

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 optimisation algorithm") OR ("modified adaptive estimation algorithmss"))~.
• Removing quotes may allow a broader search: (( modified bayesian optimisation algorithm ) or ( modified adaptive estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimisation algorithm") or ("modified adaptive estimation algorithmss"))*.
