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