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