Perhaps you should try some spelling variations:
"defined network optimisation algorithm" » "defined network optimization algorithms", "defined network estimation algorithm", "defined network estimation algorithms", "defined network optimization algorithm"
"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 ventilation algorithms") OR ("defined network optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified adaptive ventilation algorithms ) or ( defined network optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive ventilation algorithms") or ("defined network optimisation algorithm"))*.
