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 positive solutions algorithm" » "modified positive solution algorithm", "modified positive evolution algorithm", "modified positive evolutionary algorithm", "modified passive solutions algorithm", "modified adaptive solutions 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 positive solutions algorithm") OR ("defined network optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified positive solutions algorithm ) or ( defined network optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified positive solutions algorithm") or ("defined network optimisation algorithm"))*.
