Perhaps you should try some spelling variations:
"modified notion optimization algorithmsss" » "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified network optimization algorithmsss", "modified policy optimization algorithmsss", "modified allocation optimization algorithmsss"
"modified stochastic estimation algorithms" » "modified stochastic optimization algorithms", "modified stochastic estimation algorithm", "modified stochastic optimisation algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified stochastic estimation algorithms") or ("modified notion optimization algorithmsss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified stochastic estimation algorithms") OR ("modified notion optimization algorithmsss")).
• Removing quotes may allow a broader search: (( modified stochastic estimation algorithms ) or ( modified notion optimization algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic estimation algorithms") or ("modified notion optimization algorithmsss"))*.
