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