Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
ventilation algorithm » estimation algorithm, estimation algorithms, evolution algorithm
adaptive ventilation » adaptive quantization, invasive ventilation
modified adaptive » modified passive
certified » verified

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

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