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