Perhaps you should try some spelling variations:
ventilation algorithmss » estimation algorithms, estimation algorithm
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
passive ventilation » adaptive ventilation, invasive ventilation
static optimisation » static optimization, stage optimization, stochastic optimization
modified passive » modified adaptive

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified passive ventilation algorithmss ) OR ( modified static optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified passive ventilation algorithmss ) or ( modified static optimisation algorithm ))*.
