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