Perhaps you should try some spelling variations:
"modified static optimization algorithms" » "modified static optimisation algorithm", "modified static estimation algorithm", "modified static optimized algorithms", "modified stage optimization algorithms", "modified stochastic optimization algorithms", "modified staffing optimization algorithms"
"modified stochastic estimation algorithms" » "modified stochastic optimization algorithms", "modified stochastic estimation algorithm", "modified stochastic optimisation algorithm", "modified stochastic approximation 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 stochastic estimation algorithms") OR ("modified static optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified stochastic estimation algorithms ) or ( modified static optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic estimation algorithms") or ("modified static optimization algorithms"))*.
