Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified objective optimisation algorithms", "modified objective estimation algorithmss", "modified multiobjective optimization algorithms"
"verified network optimization algorithm" » "verified network optimisation algorithm", "verified network estimation algorithm", "verified network estimation algorithms", "certified network optimization algorithm", "defined network optimization algorithm"

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