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 saline solution algorithm" » "modified saline evolution algorithm", "modified saline convolution algorithms", "modified saline evolutionary algorithm", "modified caging solution algorithm", "modified male solution algorithm", "modified passive solution algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified saline solution algorithm") OR ("modified network estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified saline solution algorithm ) or ( modified network estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified saline solution algorithm") or ("modified network estimation algorithms"))*.
