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