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