Perhaps you should try some spelling variations:
"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"
"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"

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