Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
ventilation algorithm » estimation algorithm, estimation algorithms, evolution algorithm
passive ventilation » adaptive ventilation, invasive ventilation
qoe optimisation » qoe optimization, _ optimisation, game optimization
modified passive » modified adaptive
modified qoe » modified male, modified _, modified bi1

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 qoe optimisation algorithm ) OR ( modified passive ventilation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified qoe optimisation algorithm ) or ( modified passive ventilation algorithm ))*.
