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