Perhaps you should try some spelling variations:
"modified dffdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified dffdaptive estimation algorithm"
"modified deep solution algorithm" » "modified deep evolution algorithm", "modified deep convolution algorithms", "modified deep evolutionary algorithm", "modified delphi solution algorithm", "modified df solution algorithm", "modified near solution algorithm", "modified drug solution algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified dffdaptive quantization algorithm") OR ("modified deep solution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified dffdaptive quantization algorithm\") OR (\"modified deep solution algorithm\"))".
• Removing quotes may allow a broader search: (( modified dffdaptive quantization algorithm ) OR ( modified deep solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified dffdaptive quantization algorithm") OR ("modified deep solution algorithm"))*.
