Perhaps you should try some spelling variations:
ventilation algorithm » estimation algorithm, estimation algorithms, evolution algorithm
adaptive ventilation » adaptive quantization, invasive ventilation
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified adaptive » modified passive
modified early » modified male, modified near
early solution » early evolution, nacl solution

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified adaptive ventilation algorithm ) or ( modified early solution algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified adaptive ventilation algorithm ) OR ( modified early solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive ventilation algorithm ) or ( modified early solution algorithm ))*.
