Perhaps you should try some spelling variations:
"modified adamdamdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified _damdamdaptive quantization algorithm", "modified dfdamdamdaptive quantization algorithm", "modified adamdamdamdaptive quantization algorithm"
"modified a estimation algorithm" » "modified _ estimation algorithm", "modified a destination algorithm", "modified _ estimating algorithm", "modified df estimation algorithm", "modified adam estimation algorithm"

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 a estimation algorithm\") OR (\"modified adamdamdaptive quantization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified a estimation algorithm ) OR ( modified adamdamdaptive quantization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified a estimation algorithm") OR ("modified adamdamdaptive quantization algorithm"))*.
