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