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