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