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

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 algorithms") OR ("modified parameter optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified network optimisation algorithms ) or ( modified parameter optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified network optimisation algorithms") or ("modified parameter optimisation algorithm"))*.
