Perhaps you should try some spelling variations:
"modified stochastic estimation algorithm" » "modified stochastic optimization algorithm"
"modified parameter optimized algorithmss" » "modified parameter optimized algorithms", "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter optimization algorithmss"

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 algorithm") OR ("modified parameter optimized algorithmss"))~.
• Removing quotes may allow a broader search: (( modified stochastic estimation algorithm ) or ( modified parameter optimized algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic estimation algorithm") or ("modified parameter optimized algorithmss"))*.
