Perhaps you should try some spelling variations:
"modified stochastic optimization algorithms" » "modified stochastic optimisation algorithm", "modified stochastic estimation algorithms", "modified stochastic estimation algorithm", "modified stochastic optimisation algorithms", "modified stochastic estimation algorithmss"
"modified quadratic optimization algorithm" » "modified static optimization algorithm", "modified quadratic optimisation algorithm", "modified quadratic estimation algorithm", "modified quadratic estimation 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 optimization algorithms") or ("modified quadratic optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified stochastic optimization algorithms") OR ("modified quadratic optimization algorithm")).
• Removing quotes may allow a broader search: (( modified stochastic optimization algorithms ) or ( modified quadratic optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimization algorithms") or ("modified quadratic optimization algorithm"))*.
