Perhaps you should try some spelling variations:
"modified passive optimization algorithms" » "modified passive optimisation algorithm", "modified passive estimation algorithms", "modified passive estimation algorithm", "modified bayesian optimization algorithms", "modified game optimization algorithms", "modified policy optimization algorithms", "modified adaptive 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 passive optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adam approximation algorithms\") OR (\"modified passive optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified adam approximation algorithms ) OR ( modified passive optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adam approximation algorithms") OR ("modified passive optimization algorithms"))*.
