Perhaps you should try some spelling variations:
"modified parameter optimisation algorithmss" » "modified parameter optimisation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameter optimization algorithmss", "modified parameter estimation algorithmss"
"modified network optimization algorithm" » "modified network optimization algorithms", "modified network optimisation algorithm", "modified network estimation algorithm", "certified network optimization algorithm", "defined network optimization algorithm", "modified near 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 parameter optimisation algorithmss") OR ("modified network optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified parameter optimisation algorithmss ) or ( modified network optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimisation algorithmss") or ("modified network optimization algorithm"))*.
