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

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

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