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