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

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