Perhaps you should try some spelling variations:
"modified parameter optimized algorithms" » "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter optimization algorithms"
"modified adam approximation algorithms" » "modified _ approximation algorithms", "modified one approximation algorithms", "modified time approximation algorithms", "modified df approximation algorithms", "modified near approximation 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 adam approximation algorithms") or ("modified parameter optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adam approximation algorithms") OR ("modified parameter optimized algorithms"))*.
• Removing quotes may allow a broader search: (( modified adam approximation algorithms ) or ( modified parameter optimized algorithms ))*.
