Perhaps you should try some spelling variations:
ventilation algorithm » estimation algorithm, estimation algorithms, evolution algorithm
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
passive ventilation » adaptive ventilation, invasive ventilation
modified passive » modified adaptive
modified game » modified male, modified adam

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified passive ventilation algorithm ) OR ( modified game optimized algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified passive ventilation algorithm ) OR ( modified game optimized algorithms ))*.
