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