Perhaps you should try some spelling variations:
ventilation algorithm » estimation algorithm, estimation algorithms, evolution algorithm
invasive ventilation » adaptive ventilation
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified invasive » modified passive
modified time » modified bi1, modified male
time solution » time solutions, time evolution, optimal solution

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

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