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