Perhaps you should try some spelling variations:
"modified _daptive quantization algorithm" » "modified _daptive estimation algorithm", "modified adaptive quantization algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified a estimation algorithms" » "modified a estimation algorithm", "modified a optimization algorithms", "modified a optimisation algorithm", "modified _ estimation algorithms", "modified a destination algorithms", "modified _ estimating algorithms", "modified df estimation algorithms", "modified adam estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified a estimation algorithms") OR ("modified _daptive quantization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified a estimation algorithms\") OR (\"modified _daptive quantization algorithm\"))".
• Removing quotes may allow a broader search: (( modified a estimation algorithms ) OR ( modified _daptive quantization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified a estimation algorithms") OR ("modified _daptive quantization algorithm"))*.
