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