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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified adaptive ventilation algorithm ) OR ( modified positive solution algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified adaptive ventilation algorithm ) OR ( modified positive solution algorithm ))*".
