Perhaps you should try some spelling variations:
"modified objective optimization algorithmss" » "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified multiobjective optimization algorithmss", "modified objective optimization algorithmsss", "modified objective optimisation algorithmss", "modified objective estimation algorithmss"
"modified static optimization algorithm" » "modified static optimization algorithms", "modified static optimisation algorithm", "modified static estimation algorithm", "modified stage optimization algorithm", "modified stochastic optimization algorithm", "modified staffing optimization 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 objective optimization algorithmss") or ("modified static optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimization algorithmss") OR ("modified static optimization algorithm")).
• Removing quotes may allow a broader search: (( modified objective optimization algorithmss ) or ( modified static optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithmss") or ("modified static optimization algorithm"))*.
