Perhaps you should try some spelling variations:
"designed network approximation algorithm" » "designed network approximation algorithms", "defined network approximation algorithm"
"modified adam optimisation algorithm" » "modified adam optimization algorithms", "modified adam estimation algorithm", "modified adam estimation algorithms", "modified _ optimisation algorithm", "modified game optimization algorithm", "modified df optimisation algorithm", "modified near optimisation algorithm"

Try widening your search to All Fields.

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