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