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