Perhaps you should try some spelling variations:
"modified notion estimation algorithmss" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion estimation algorithms", "modified notion optimization algorithmss", "modified notion optimisation algorithms", "modified motion estimation algorithmss"
"modified risk estimation algorithms" » "modified risk estimation algorithm", "modified risk optimization algorithms", "modified risk optimisation algorithm", "modified pose estimation algorithms", "modified bi1 estimation 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 notion estimation algorithmss") OR ("modified risk estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified notion estimation algorithmss ) or ( modified risk estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion estimation algorithmss") or ("modified risk estimation algorithms"))*.
