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