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