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

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