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