Perhaps you should try some spelling variations:
"modified notion optimization algorithmss" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified notion optimisation algorithms", "modified notion estimation algorithmss", "modified network optimization algorithmss", "modified policy optimization algorithmss", "modified allocation optimization algorithmss"
"modified global optimization algorithms" » "modified global optimisation algorithm", "modified global estimation algorithms", "modified global estimation algorithm"

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