Perhaps you should try some spelling variations:
ventilation algorithm » estimation algorithm, estimation algorithms, evolution algorithm
adaptive ventilation » adaptive quantization, invasive ventilation
objective optimized » objective optimal, objective optimization
optimized algorithm » optimized algorithms, optimizer algorithms
modified adaptive » modified passive

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 ( modified objective optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive ventilation algorithm ) or ( modified objective optimized algorithm ))*.
