Perhaps you should try some spelling variations:
"modified adamdamdaptive quantization algorithm" » "modified adaptive quantization algorithm"
"modified model estimation algorithm" » "modified pose estimation algorithm", "modified cover estimations algorithm", "modified motion estimation algorithm", "modified male 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 adamdamdaptive quantization algorithm") OR ("modified model estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified adamdamdaptive quantization algorithm ) or ( modified model estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adamdamdaptive quantization algorithm") or ("modified model estimation algorithm"))*.
