Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm"
"modified adam approximation algorithm" » "modified adam approximation algorithms", "modified _ approximation algorithm", "modified one approximation algorithm", "modified time approximation algorithm", "modified df approximation algorithm", "modified near approximation algorithm"

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 parameters optimization algorithms") OR ("modified adam approximation algorithm"))~.
• Removing quotes may allow a broader search: (( modified parameters optimization algorithms ) or ( modified adam approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithms") or ("modified adam approximation algorithm"))*.
