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