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