Perhaps you should try some spelling variations:
quantization algorithm » estimation algorithm
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
adaptive quantization » adaptive ventilation
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 quantization algorithm ) or ( modified parameter optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified adaptive quantization algorithm ) OR ( modified parameter optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive quantization algorithm ) or ( modified parameter optimisation algorithm ))*.
