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

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

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