Perhaps you should try some spelling variations:
"verified network optimisation algorithm" » "verified network optimization algorithms", "verified network estimation algorithms", "verified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation 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.

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