Perhaps you should try some spelling variations:
"modified adam estimation algorithms" » "modified adam estimation algorithm", "modified adam optimization algorithms", "modified adam optimisation algorithm", "modified df estimation algorithms", "modified near estimation algorithms"
"modified bayesian optimizer algorithms" » "modified bayesian optimized algorithms", "modified bayesian optimized algorithm", "modified bayesian optimization algorithms"

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 adam estimation algorithms") OR ("modified bayesian optimizer algorithms"))~.
• Removing quotes may allow a broader search: (( modified adam estimation algorithms ) or ( modified bayesian optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam estimation algorithms") or ("modified bayesian optimizer algorithms"))*.
