Perhaps you should try some spelling variations:
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive 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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive optimization algorithms") OR ("modified adaptive ventilation algorithms"))~.
• Removing quotes may allow a broader search: (( modified adaptive optimization algorithms ) or ( modified adaptive ventilation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive optimization algorithms") or ("modified adaptive ventilation algorithms"))*.
