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 changing optimisation algorithms" » "modified changing optimization algorithms", "modified changing estimation algorithms", "modified changing estimation algorithm", "modified changing optimization algorithmss", "modified changing estimation algorithmss", "modified staffing optimization algorithms", "modified caging optimisation 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 optimisation algorithm") OR ("modified changing optimisation algorithms"))~.
• Removing quotes may allow a broader search: (( modified stochastic optimisation algorithm ) or ( modified changing optimisation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimisation algorithm") or ("modified changing optimisation algorithms"))*.
