Perhaps you should try some spelling variations:
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified devices solution algorithm" » "modified devices evolution algorithm", "modified devices convolution algorithms", "modified devices evolutionary algorithm", "modified traces solution algorithm"

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 adaptive quantization algorithm\") OR (\"modified devices solution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithm ) OR ( modified devices solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive quantization algorithm") OR ("modified devices solution algorithm"))*.
