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

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