Perhaps you should try some spelling variations:
"verified network optimization algorithms" » "verified network optimisation algorithm", "verified network estimation algorithms", "verified network estimation algorithm", "certified network optimization algorithms", "defined network optimization algorithms"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms"

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