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 df optimisation algorithms" » "modified df optimization algorithms", "modified df estimation algorithms", "modified df estimation algorithm", "modified df optimization algorithmss", "modified df estimation algorithmss", "modified _ optimisation algorithms", "modified _ optimization algorithms", "modified qoe optimization algorithms", "modified adam optimisation algorithms", "modified bi1 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 df optimisation algorithms"))~.
• Removing quotes may allow a broader search: (( modified stochastic optimisation algorithm ) or ( modified df optimisation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimisation algorithm") or ("modified df optimisation algorithms"))*.
