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