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

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