Perhaps you should try some spelling variations:
"modified notion optimization algorithmsssss" » "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified network optimization algorithmsssss", "modified policy optimization algorithmsssss", "modified allocation optimization algorithmsssss"
"modified parameters estimation algorithm" » "modified parameter estimation algorithm", "modified parameter estimates algorithm", "modified parameter optimization algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameters estimation algorithm") or ("modified notion optimization algorithmsssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters estimation algorithm") OR ("modified notion optimization algorithmsssss"))*.
• Removing quotes may allow a broader search: (( modified parameters estimation algorithm ) or ( modified notion optimization algorithmsssss ))*.
