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