Perhaps you should try some spelling variations:
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithm"
"modified network estimation algorithmsss" » "modified network estimation algorithms", "modified network estimation algorithm", "modified network optimization algorithmsss", "certified network estimation algorithmsss", "defined network estimation algorithmsss", "modified near estimation algorithmsss"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimization algorithm") OR ("modified network estimation algorithmsss"))~.
• Removing quotes may allow a broader search: (( modified parameters optimization algorithm ) or ( modified network estimation algorithmsss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithm") or ("modified network estimation algorithmsss"))*.
