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