Perhaps you should try some spelling variations:
ventilation algorithm » estimation algorithm, estimation algorithms
passive ventilation » adaptive ventilation, invasive ventilation
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
positive evolution » positive solutions
modified positive » modified adaptive
modified passive » modified adaptive

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified passive ventilation algorithm ) OR ( modified positive evolution algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified passive ventilation algorithm ) OR ( modified positive evolution algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified passive ventilation algorithm ) OR ( modified positive evolution algorithm ))*.
