Perhaps you should try some spelling variations:
"modified notion estimation algorithmssss" » "modified notion estimation algorithms", "modified notion estimation algorithm", "modified motion estimation 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"

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