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

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 parameter optimisation algorithm") OR ("modified network optimization algorithmsss"))~.
• Removing quotes may allow a broader search: (( modified parameter optimisation algorithm ) or ( modified network optimization algorithmsss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimisation algorithm") or ("modified network optimization algorithmsss"))*.
