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

Try widening your search to All Fields.

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

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