Perhaps you should try some spelling variations:
"modified 3d optimization algorithms" » "modified 3d optimisation algorithm", "modified 3d estimation algorithms", "modified 3d estimation algorithm", "modified _ optimization algorithms", "modified qoe optimization algorithms", "modified _ optimisation algorithms", "modified df optimization algorithms", "modified adam optimization algorithms"
"modified dfdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified dfdaptive 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 dfdaptive quantization algorithm") OR ("modified 3d optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified dfdaptive quantization algorithm ) or ( modified 3d optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified dfdaptive quantization algorithm") or ("modified 3d optimization algorithms"))*.
