Perhaps you should try some spelling variations:
"modified adamdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified adamdaptive estimation algorithm"
"modified df approximation algorithms" » "modified _ approximation algorithms", "modified one approximation algorithms", "modified time approximation algorithms", "modified adam approximation algorithms", "modified bi1 approximation 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 adamdaptive quantization algorithm\") OR (\"modified df approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified adamdaptive quantization algorithm ) OR ( modified df approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adamdaptive quantization algorithm") OR ("modified df approximation algorithms"))*.
