Perhaps you should try some spelling variations:
"modified caging convolution algorithm" » "modified caging convolution algorithms", "modified caging evolution algorithm", "modified caging solution algorithm", "modified learning convolution algorithm"
"modified invasive estimation algorithms" » "modified invasive estimation algorithm", "modified invasive optimization algorithms", "modified invasive optimisation algorithm", "modified invasive ventilation algorithms", "modified passive estimation algorithms"

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 convolution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified invasive estimation algorithms ) OR ( modified caging convolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive estimation algorithms") OR ("modified caging convolution algorithm"))*.
