Perhaps you should try some spelling variations:
"modified invasive ventilation algorithm" » "modified invasive estimation algorithm", "modified invasive estimation algorithms", "modified invasive evolution algorithm", "modified adaptive ventilation algorithm", "modified passive ventilation algorithm"
"modified learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion 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 invasive ventilation algorithm") OR ("modified learning method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified invasive ventilation algorithm\") OR (\"modified learning method algorithm\"))".
• Removing quotes may allow a broader search: (( modified invasive ventilation algorithm ) OR ( modified learning method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive ventilation algorithm") OR ("modified learning method algorithm"))*.
