Perhaps you should try some spelling variations:
quantization algorithm » estimation algorithm
adaptive quantization » adaptive ventilation
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified adaptive » modified passive
modified ohca » modified orca
ohca solution » nacl solution

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified ohca solution algorithm ) OR ( modified adaptive quantization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified ohca solution algorithm ) OR ( modified adaptive quantization algorithm ))*.
