Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
ventilation algorithm » estimation algorithm, estimation algorithms, evolution algorithm
quantile optimization » quantile estimation, quadratic optimization, static optimization
passive ventilation » adaptive ventilation, invasive ventilation
modified quantile » 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 quantile optimization algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified passive ventilation algorithm ) OR ( modified quantile optimization algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( modified passive ventilation algorithm ) OR ( modified quantile optimization algorithms ))*.
