Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
ventilation algorithms » estimation algorithms, estimation algorithm, convolution algorithms
passive ventilation » adaptive ventilation, invasive ventilation
male optimisation » game optimization, market optimization, stage optimization
modified passive » modified adaptive

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