Perhaps you should try some spelling variations:
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive optimization algorithms"
"modified df approximation algorithms" » "modified _ approximation algorithms", "modified one approximation algorithms", "modified time approximation algorithms", "modified adam approximation algorithms", "modified bi1 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 adaptive optimization algorithms") OR ("modified df approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive optimization algorithms\") OR (\"modified df approximation algorithms\"))".
• Removing quotes may allow a broader search: (( modified adaptive optimization algorithms ) OR ( modified df approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive optimization algorithms") OR ("modified df approximation algorithms"))*.
