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