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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified adaptive ventilation algorithms ) OR ( modified bi1 optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive ventilation algorithms ) OR ( modified bi1 optimisation algorithm ))*.
