Perhaps you should try some spelling variations:
"modified stochastic optimisation algorithm" » "modified stochastic optimization algorithm", "modified static optimization algorithm", "modified stochastic configuration algorithm", "modified stochastic optimization algorithms", "modified stochastic estimation algorithm", "modified stochastic estimation algorithms"
"modified static estimation algorithmss" » "modified static estimation algorithms", "modified static estimation algorithm", "modified static optimization algorithms", "modified static optimization algorithmss"

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