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