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

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