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