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

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 optimization algorithms") or ("modified notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified stochastic optimization algorithms") OR ("modified notion optimization algorithms"))*.
• Removing quotes may allow a broader search: (( modified stochastic optimization algorithms ) or ( modified notion optimization algorithms ))*.
