Perhaps you should try some spelling variations:
"modified dfdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified dfdaptive estimation algorithm"
"modified via estimation algorithms" » "modified via estimation algorithm", "modified via optimization algorithms", "modified via optimisation algorithm", "modified risk estimation algorithms", "modified _ estimation algorithms", "modified bi1 estimation algorithms", "modified adam estimation algorithms", "modified near 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 via estimation algorithms") OR ("modified dfdaptive quantization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified via estimation algorithms\") OR (\"modified dfdaptive quantization algorithm\"))".
• Removing quotes may allow a broader search: (( modified via estimation algorithms ) OR ( modified dfdaptive quantization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified via estimation algorithms") OR ("modified dfdaptive quantization algorithm"))*.
