Perhaps you should try some spelling variations:
"modified dfdamdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified dfdamdaptive estimation algorithm"
"modified via optimization algorithms" » "modified via optimisation algorithm", "modified via estimation algorithms", "modified via estimation algorithm", "modified _ optimization algorithms", "modified qoe optimization algorithms", "modified stage optimization algorithms", "modified bi1 optimization algorithms", "modified adam optimization algorithms", "modified near optimization 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 dfdamdaptive quantization algorithm\") OR (\"modified via optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified dfdamdaptive quantization algorithm ) OR ( modified via optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified dfdamdaptive quantization algorithm") OR ("modified via optimization algorithms"))*.
