Perhaps you should try some spelling variations:
"modified passive quantization algorithm" » "modified passive estimation algorithm", "modified adaptive quantization algorithm"
"modified device simulation algorithms" » "modified device estimation algorithms", "modified device optimization algorithms", "modified device estimation algorithm", "modified policy simulation algorithms", "modified via simulation 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 device simulation algorithms") OR ("modified passive quantization algorithm"))~.
• Removing quotes may allow a broader search: (( modified device simulation algorithms ) or ( modified passive quantization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified device simulation algorithms") or ("modified passive quantization algorithm"))*.
