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 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.

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