Perhaps you should try some spelling variations:
"modified passive quantization algorithm" » "modified passive estimation algorithm", "modified adaptive quantization algorithm"
"modified adaptive estimation algorithms" » "modified adaptive estimation algorithm", "modified adaptive optimization algorithms", "modified adaptive optimisation algorithm", "modified adaptive ventilation algorithms", "modified quantile estimation algorithms", "modified adaptive quantization algorithms"

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