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