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