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