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