Perhaps you should try some spelling variations:
"modified passive quantization algorithms" » "modified passive estimation algorithms", "modified passive optimization algorithms", "modified adaptive quantization algorithms"
"modified stochastic optimisation algorithm" » "modified stochastic optimization algorithm", "modified static optimization algorithm", "modified stochastic configuration algorithm", "modified stochastic optimization algorithms", "modified stochastic estimation algorithm", "modified stochastic estimation algorithms"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified passive quantization algorithms") or ("modified stochastic optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified passive quantization algorithms") OR ("modified stochastic optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified passive quantization algorithms ) or ( modified stochastic optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified passive quantization algorithms") or ("modified stochastic optimisation algorithm"))*.
