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