Perhaps you should try some spelling variations:
"modified bayesian optimization algorithms" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "modified bayesian estimation algorithm"
"modified network estimation algorithmss" » "modified network estimation algorithms", "modified network estimation algorithm", "modified network optimization algorithmss", "certified network estimation algorithmss", "defined network estimation algorithmss", "modified near 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 optimization algorithms") OR ("modified network estimation algorithmss"))~.
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithms ) or ( modified network estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimization algorithms") or ("modified network estimation algorithmss"))*.
