Perhaps you should try some spelling variations:
"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"
"defined network optimisation algorithm" » "defined network optimization algorithms", "defined network estimation algorithm", "defined network estimation algorithms", "defined network optimization algorithm", "designed network optimisation algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("defined network optimisation algorithm") or ("modified adam approximation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("defined network optimisation algorithm") OR ("modified adam approximation algorithm")).
• Removing quotes may allow a broader search: (( defined network optimisation algorithm ) or ( modified adam approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("defined network optimisation algorithm") or ("modified adam approximation algorithm"))*.
