Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
ventilation algorithms » estimation algorithms, estimation algorithm, convolution algorithms
invasive ventilation » adaptive ventilation
market optimization » game optimization, parameter optimization, market capitalization
modified invasive » modified passive
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 invasive ventilation algorithms ) OR ( modified market optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified invasive ventilation algorithms ) or ( modified market optimization algorithms ))*.
