Perhaps you should try some spelling variations:
"modified invasive optimization algorithms" » "modified invasive optimisation algorithm", "modified invasive estimation algorithms", "modified invasive estimation algorithm", "modified passive optimization algorithms"
"modified network optimized algorithm" » "modified network optimized algorithms", "modified network optimizer algorithms", "modified network optimization algorithm", "certified network optimized algorithm", "defined network optimized algorithm", "modified near optimized algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified network optimized algorithm\") OR (\"modified invasive optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified network optimized algorithm ) OR ( modified invasive optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified network optimized algorithm") OR ("modified invasive optimization algorithms"))*.
