Perhaps you should try some spelling variations:
"modified stochastic approximation algorithms" » "modified diophantine approximation algorithms", "modified stochastic optimization algorithms"
"modified adam estimation algorithms" » "modified adam estimation algorithm", "modified adam optimization algorithms", "modified adam optimisation algorithm", "modified df estimation algorithms", "modified near estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified stochastic approximation algorithms") or ("modified adam estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified stochastic approximation algorithms") OR ("modified adam estimation algorithms")).
• Removing quotes may allow a broader search: (( modified stochastic approximation algorithms ) or ( modified adam estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic approximation algorithms") or ("modified adam estimation algorithms"))*.
