Perhaps you should try some spelling variations:
ventilation algorithm » estimation algorithm, estimation algorithms, evolution algorithm
adaptive ventilation » adaptive quantization, invasive ventilation
modified adaptive » modified passive
emotion algorithm » evolution algorithm, estimation algorithm, predation algorithm
learning emotion » learning method

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 algorithm ) OR ( machine learning emotion algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive ventilation algorithm ) or ( machine learning emotion algorithm ))*.
