Perhaps you should try some spelling variations:
"modified dfdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified dfdaptive estimation algorithm"
"modified a estimation algorithms" » "modified a estimation algorithm", "modified a optimization algorithms", "modified a optimisation algorithm", "modified _ estimation algorithms", "modified a destination algorithms", "modified _ estimating algorithms", "modified df estimation algorithms", "modified adam estimation algorithms"

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