Perhaps you should try some spelling variations:
"modified invasive estimation algorithms" » "modified invasive estimation algorithm", "modified invasive optimization algorithms", "modified invasive optimisation algorithm", "modified invasive ventilation algorithms", "modified passive estimation algorithms"
"modified adam approximation algorithms" » "modified _ approximation algorithms", "modified one approximation algorithms", "modified time approximation algorithms", "modified df approximation algorithms", "modified near approximation 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 adam approximation algorithms") OR ("modified invasive estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adam approximation algorithms\") OR (\"modified invasive estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified adam approximation algorithms ) OR ( modified invasive estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adam approximation algorithms") OR ("modified invasive estimation algorithms"))*.
