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