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