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 algorithm" » "verified network optimized algorithms", "verified network optimizer algorithms", "verified network optimization algorithm", "certified network optimized algorithm", "defined network optimized algorithm"

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: "((\"verified network optimized algorithm\") OR (\"modified multiobjective estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( verified network optimized algorithm ) OR ( modified multiobjective estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("verified network optimized algorithm") OR ("modified multiobjective estimation algorithms"))*.
