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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"defined network approximation algorithm\") OR (\"modified adam optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( defined network approximation algorithm ) OR ( modified adam optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("defined network approximation algorithm") OR ("modified adam optimisation algorithm"))*.
