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