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

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