Perhaps you should try some spelling variations:
"modified adamdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified _damdaptive quantization algorithm", "modified dfdamdaptive quantization algorithm", "modified adamdamdaptive 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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified a estimation algorithm") OR ("modified adamdaptive quantization algorithm"))~.
• Removing quotes may allow a broader search: (( modified a estimation algorithm ) or ( modified adamdaptive quantization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified a estimation algorithm") or ("modified adamdaptive quantization algorithm"))*.
