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