Perhaps you should try some spelling variations:
"designed network optimization algorithm" » "designed network optimization algorithms", "designed network optimisation algorithm", "designed network estimation algorithm", "defined network optimization algorithm"
"modified caging convolution algorithms" » "modified caging evolution algorithm", "modified caging solution algorithm", "modified learning convolution 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: "((\"designed network optimization algorithm\") OR (\"modified caging convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( designed network optimization algorithm ) OR ( modified caging convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("designed network optimization algorithm") OR ("modified caging convolution algorithms"))*.
