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