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

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified static optimisation algorithmss") or ("modified objective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified static optimisation algorithmss") OR ("modified objective optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified static optimisation algorithmss ) or ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified static optimisation algorithmss") or ("modified objective optimisation algorithm"))*.
