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