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

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

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