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 algorithmss" » "verified network estimation algorithms", "verified network estimation algorithm", "verified network optimization algorithms", "verified network optimization algorithmss", "certified network estimation algorithmss", "defined network estimation algorithmss"

You may be able to get more results by adjusting your search query.

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