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