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 adaptive ventilation algorithms" » "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive convolution algorithms", "modified adaptive quantization algorithms", "modified invasive 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 adaptive ventilation algorithms") OR ("modified notion optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive ventilation algorithms\") OR (\"modified notion optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified adaptive ventilation algorithms ) OR ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive ventilation algorithms") OR ("modified notion optimization algorithms"))*.
