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

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