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