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

You may be able to get more results by adjusting your search query.

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