Perhaps you should try some spelling variations:
"modified stochastic approximation algorithms" » "modified diophantine approximation algorithms", "modified stochastic optimization algorithms"
"modified static optimization algorithms" » "modified static optimisation algorithm", "modified static estimation algorithms", "modified static estimation algorithm", "modified stage optimization algorithms", "modified stochastic optimization algorithms", "modified staffing optimization algorithms"

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

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