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