Perhaps you should try some spelling variations:
"modified adaptive optimisation algorithm" » "modified adaptive optimization algorithms", "modified adaptive estimation algorithm", "modified passive optimisation algorithm"
"modified adam estimation algorithms" » "modified adam estimation algorithm", "modified adam optimization algorithms", "modified adam approximation algorithms", "modified df estimation algorithms", "modified near estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive optimisation algorithm") OR ("modified adam estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive optimisation algorithm\") OR (\"modified adam estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified adaptive optimisation algorithm ) OR ( modified adam estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive optimisation algorithm") OR ("modified adam estimation algorithms"))*.
