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