Perhaps you should try some spelling variations:
"modified _damdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified _damdaptive estimation 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 _damdaptive quantization algorithm") OR ("modified a estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified _damdaptive quantization algorithm\") OR (\"modified a estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified _damdaptive quantization algorithm ) OR ( modified a estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified _damdaptive quantization algorithm") OR ("modified a estimation algorithms"))*.
