Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithm\") OR (\"verified network optimized algorithms\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) OR ( verified network optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") OR ("verified network optimized algorithms"))*.
