Perhaps you should try some spelling variations:
ventilation algorithmss » estimation algorithms, estimation algorithm
stochastic optimisation » stochastic optimization, static optimization, stochastic configuration
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
invasive ventilation » adaptive ventilation
modified invasive » 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 invasive ventilation algorithmss ) or ( modified stochastic optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified invasive ventilation algorithmss ) OR ( modified stochastic optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified invasive ventilation algorithmss ) or ( modified stochastic optimisation algorithm ))*.
