Perhaps you should try some spelling variations:
"modified parameter estimation algorithmss" » "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimates algorithmss", "modified parameter optimization algorithmss"
"modified network optimized algorithms" » "modified network optimized algorithm", "modified network optimizer algorithms", "modified network optimization algorithms", "certified network optimized algorithms", "defined network optimized algorithms", "modified near optimized 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 network optimized algorithms") or ("modified parameter estimation algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network optimized algorithms") OR ("modified parameter estimation algorithmss")).
• Removing quotes may allow a broader search: (( modified network optimized algorithms ) or ( modified parameter estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified network optimized algorithms") or ("modified parameter estimation algorithmss"))*.
