Perhaps you should try some spelling variations:
"certified network optimisation algorithm" » "certified network optimization algorithms", "certified network estimation algorithm", "certified network estimation algorithms", "certified network optimization algorithm", "verified network optimisation algorithm"
"modified parameter optimized algorithm" » "modified parameter optimization algorithm", "modified parameter optimized algorithms", "modified parameter optimizer 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: (("certified network optimisation algorithm") OR ("modified parameter optimized algorithm"))~.
• Removing quotes may allow a broader search: (( certified network optimisation algorithm ) or ( modified parameter optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("certified network optimisation algorithm") or ("modified parameter optimized algorithm"))*.
