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

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 optimization algorithms") OR ("modified static optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified stochastic optimization algorithms ) or ( modified static optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimization algorithms") or ("modified static optimisation algorithm"))*.
