Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
ventilation algorithms » estimation algorithms, estimation algorithm, convolution algorithms
adaptive ventilation » adaptive quantization, invasive ventilation
caging optimization » staffing optimization
modified adaptive » modified passive

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 algorithms ) or ( modified caging optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified adaptive ventilation algorithms ) OR ( modified caging optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive ventilation algorithms ) or ( modified caging optimization algorithm ))*.
