Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified invasive ventilation algorithms" » "modified invasive estimation algorithms", "modified invasive estimation algorithm", "modified invasive convolution algorithms", "modified adaptive ventilation algorithms", "modified passive ventilation 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 invasive ventilation algorithms") or ("modified notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified invasive ventilation algorithms") OR ("modified notion optimization algorithms")).
• Removing quotes may allow a broader search: (( modified invasive ventilation algorithms ) or ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive ventilation algorithms") or ("modified notion optimization algorithms"))*.
