Perhaps you should try some spelling variations:
ventilation algorithms » estimation algorithm, convolution algorithms
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
adaptive ventilation » adaptive quantization, invasive ventilation
modified adaptive » modified passive
modified adam » modified df, modified near

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 ( modified adam estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive ventilation algorithms ) or ( modified adam estimation algorithms ))*.
